is the gradient or slope of the line. The constant, 𝑐, is the 𝑦-intercept. This is the value where the line crosses the 𝑦-axis. Let's look at an example question. A straight line passes ...

In order to work with gradients and straight lines successfully ... The gradient of the line is 3 Find the \(y\)-intercept of the line. The value where the line crosses the \(y\)-axis is 1 ...

so the 𝑦-intercept is 3. Back to top Equation of a line from a graph – interactive activity Working with the general equation of a straight line, 𝑦 = 𝑚𝑥 + 𝑐, use the interactive ...

Linear regression is graphically depicted using a straight line; the slope defines how the ... more complex relationships. A multiple regression formula has multiple slopes (one for each variable) and one y-intercept. It is interpreted the same as a ...

Any equation that can be rearranged into the form \(y = mx + c\), will have a straight line graph. \(m\) is the gradient, or steepness of the graph, and \(c\) is the \(y\)-intercept, or where the ...

Find the gradient and y-intercept for the straight line with equation \(2x + y - 13 = 0\). Rearrange the equation into the form \(y = mx + c\) using the algebraic rules for solving equations.

The straight line through two points will have an equation in the form \(y = mx + c\). Then, we can find the value of \(c\), the \(y\)-intercept, by substituting the coordinates of one point into ...

Any equation that can be rearranged into the form \(y = mx + c\), will have a straight line graph. \(m\) is the gradient, or steepness of the graph, and \(c\) is the \(y\)-intercept, or where the ...
