11-85.

Paula graphed a line and found that f(−2) = 5 and f(0) = 2. Graph this line and find its equation. Homework Help ✎

f(−2) = 5 means (−2,5) is a point on the line. Also, (0,2) is a point on the line.

Graph the points on a set of axis, then draw the line.

To find the equation, make a slope triangle to find the slope and the y-intercept. Substitute these values into the equation of a line.
