3-109.

Find an equation of the line with slope

There are two ways to solve this. You can substitute the slope for *m* in the equation below, substitute the *x* and *y* coordinates of the given point for *x* and *y*, and then solve for *b*.*y* = *mx* + *b*

You can also graph the point (10, 9), use the slope to graph a second point, draw the line, and find the *y*-intercept.

Use the eTool below to solve the problem.
