The line with equation y=1/3x+4 passes through the points (3,5) and (9,7). The first point (3,5) → (x1,y1) The first point (9,7) → (x2,y2)
The slope intercept form of the equation: y = 3x - 5. Problem 7. A line with a slope of ½ and a y-intercept of 7. Show Answer. In the general form: y = mx + b m = slope = ½ b = the y intercept = 7 The slope intercept form of the equation: y = ½x + 7. Worksheet (Worksheet with ...
Sometimes, instead of two points, we are given the equation of a line. To determine the slope, we rewrite the equation in slope-intercept form: y = mx + b …..(i) For example, let us consider the equation: y = 4x – 7. By comparing it to the equation (i), we get. m = 4. Thus, the slope is m = 4. From a Graph

Practice Questions on Slope Formula. Q1. Calculate the slope of a line passing through the points (2, 3) and (5, 7) Q2. Given the equation of a line: y = 3x – 11, what is its slope? Q3. If the slope of a line is 5/6 and it passes through the point (2, 5) what is the equation of the line in slope-intercept form? Q4.
Example 2: Finding the Slope and Y-Intercept from an Equation. Suppose you’re given the equation: y = −3x + 4 To find the slope and y-intercept, compare y = −3x + 4 with y = mx + b:. In y = −3x + 4, – 3 is with x so slope (m) is – 3.; The y-intercept (b) is 4.This tells us the line is steep and slopes downward, crossing the y-axis at (0, 4).
Write the equation of the given line in slope-intercept form to determine its slope, then use that same slope and your point in the point-slope formula. 3x - y = 5 - y = - 3x + 5. y = 3x - 5. m = 3, b = - 5. So the slope of the given line is 3. Parallel lines have equal slopes, so the slope of our line is also 3. Our line also goes through the ...
Example 1: Write the equation of the line in slope-intercept form with a slope of [latex] – \,5[/latex] and a [latex]y[/latex]-intercept of [latex]3[/latex]. The needed information to write the equation of the line in the form [latex]y = mx + b[/latex] are clearly given in the problem since
Example One. The slope of a line going through the point (1, 2) and the point (4, 3) is $$ \frac{1}{3}$$.. Remember: difference in the y values goes in the numerator of formula, and the difference in the x values goes in denominator of the formula.
The slope of a line, "m" in the equation for a line of the form y = mx + b, can be found using the slope formula as long as at least two points on the line are known. It can be written as follows: Example. Given two points, (1, 3) and (4, 7), we can plug them into the formula to find the slope:
Express \(3x+5y=30\) in slope-intercept form and then identify the slope and \(y\)-intercept. Solution: Begin by solving for \(y\). To do this, apply the properties of equality to first isolate \(5y\) and then divide both sides by \(5\). ... Given any two points on a line, we can algebraically calculate the slope using the slope formula, \(m ...
Thus, the slope formula is given as: Slope = m = (y 2 - y 1)/(x 2 - x 1) Slope Equation. As we discussed in the previous section, the slope formula can be used to determine the slope of any line. The equation that can be used in finding this slope can therefore written as, m = rise/run = tanθ = Δy/Δx = (y 2 - y 1)/(x 2 - x 1)
The point-slope form of the equation of a straight line is: y y1 = m(x x1). The equation is useful when we know: one point on the line: (x1, y1). m,. ... y = 3x − 9 + 2. y = 3x − 7. Example 2: m = −3 1 = −3. y − y 1 = m(x − x 1) We can pick any point for (x 1, y 1), so let's choose (0,0), and we have:
The slope formula is as follows: Rise over run. ... -3x - 2 has a slope of -3, and y = ⅓x + 1 has a slope of ⅓. -3 and ⅓ are opposite reciprocals, so the equations are perpendicular: Linear equations. Equation of a line. Intercept. Linear. Linear regression.
2. Point-Slope Form: y − y 1 = m(x − x 1) This form is useful when you know one point on the line and the slope. It helps you create the equation when the y-intercept isn’t given. m represents the slope of the line. (x 1, y 1) is the point on the line. Example 2: The slope (m) of a line is 3 and it passes through the point (1, 2).
