3-109.

Find an equation of the line with slope passing through the point (10, 9). 3-109 HW eTool (Desmos). Homework Help ✎.

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.
