Given A(4, 2) and B(-1, y) and the graph
of line t below, find the value of y so that
AB It.

y = 9

Step-by-step explanation:

To solve this question we will use the property of perpendicular lines,

Where and are the slopes of two lines perpendicular to each other.

Slope of a line passing through two points and is given by,

Slope of a line which passes through the points A(4, 2) and B(-1, y) will be

Slope of the line given in the graph [passing through (2, 4) and (-5, -1)]

From the property of perpendicular lines,

5y - 10 = 35

5y = 45

y = 9
