Graph y=x. Step 1. Use the slope-intercept form to find the slope and y-intercept. Tap for more steps... Step 1.1. The slope-intercept form is , where is the slope and is the y-intercept. Step 1.2. Find the values of and using the form . Step 1.3. The slope of the line is the value of , and the y-intercept is the value of . Slope:
For example, when x is 1: y = 2×1 + 1 = 3. So when x=1 we have y=3. Check for yourself that x=1 and y=3 is actually on the line. Or we could choose another value for x, such as 7: y = 2×7 + 1 = 15. So when x=7 we have y=15
The line y = x is not just a theoretical concept; it has practical applications. For example, in real life, if you are comparing two quantities that are always equal, like the distance traveled and the time taken at a constant speed of 1 unit per time unit, the relationship can be represented by y = x. Conclusion. The line y = x is a ...

For example the command 2x @ 3 evaluates the expression 2x for x=3, which is equal to 2*3 or 6. Algebra Calculator can also evaluate expressions that contain variables x and y. To evaluate an expression containing x and y, enter the expression you want to evaluate, followed by the @ sign and an ordered pair containing your x-value and y-value.
It's just a convention, people decided that this y = f(x) means, the value of y at each value of the function f by changing x, in your case the name of the function is y, but you can call it whatever you want, f(x),y(x),t(x),z(x),cat(x),dog(x)... ecc. In your case you have called your function with the same graphical symbol of the result.
y - y 1 = m(x - x 1) where (x 1, y 1) represent a point on the line, and m is the slope. Like slope-intercept form, it is also useful for graphing, and has the benefit of being usable using any point on the line rather than just the y-intercept specifically, as is the case with slope-intercept form. Standard form
If we denote any other point on the line as P(x, y) (see Figure 7.11 b), by the slope formula. Equation (2) is called the point-slope form for a linear equation. In Equation (2), m, x 1 and y 1 are known and x and y are variables that represent the coordinates of any point on the line. Thus, whenever we know the slope of a line and a point on ...
Graph the line y=x using the slope and y-intercept. https://www.openalgebra.com/How to graph a more complicated example on YouTube: https://youtu.be/EQmkiFIW...
Minus one is less than or equal to x, which is less than or equal to three., Draw the graph of 𝒚 = 2𝒙 – 5 for values of 𝒙 from -1 to 3. This is written as the inequality -1 ≤ 𝒙 ≤ 3
Example: (x−1)/(x 2 −9) On the page Rational Expressions we do some work to discover that the function: crosses the x-axis at 1, crosses the y-axis at 1/9, has vertical asymptotes (where it heads towards minus/plus infinity) at −3 and +3; The result is that we can make this sketch: Sketch of (x−1)/(x 2 −9) from Rational Expressions.

Type your algebra problem into the text box. For example, enter 3x+2=14 into the text box to get a step-by-step explanation of how to solve 3x+2=14.
what is on the left (x − 2) equals what is on the right (4) So an equation is like a statement "this equals that" What is a Solution? A Solution is a value we can put in place of a variable (such as x) that makes the equation true. Example: x − 2 = 4. When we put 6 in place of x we get:
