Which line has an equation of y=-5x+4 in slope-intercept form? a line passing through the points (1, 9) and (3, 19) a line passing through the points (2, –14) and (4, –24) a line passing through the points (1, 1) and (3, 11) a line passing through the points (2, –6) and (4, –16)

You can figure the line for each pair of points, or you can try the points in the equation you have and see which are on the line.

First x=1, y=-5×1 +4 = -1 . . . not 9. (1, 9) is not a point on the line

Second x=2, y=-5×2 +4 = -6 . . . not -14. (2, 14) is not a point on the line

Third (see the calculation for the first answer) . . . -1 ≠ 1. (1, 1) is not a point on the line

Fourth (see the calculation for the second answer) We know that (2, -6) is on the given line. Checking (4, -16), we find it is as well.

The appropriate choice is the 4th

... a line passing through the points (2, -6) and (4, -16)
