Aline with a slope of 1/4 passes through the points (9, -8) and (5, d). what is the value for?

d = -9

Explanation:
The slope of the line can be calculated using the following formula:
slope =

We are given:
slope =
point (9,-8) representing (x1,y1)
point (5,d) representing (x2,y2)

Substitute with the givens in the above equation and solve for d as follows:
slope =
=
=
4(d+8) = -4
d + 8 = -1
d = -1 - 8
d = -9

Hope this helps :)
