If the gradient of the line joining the points [4,-9]and [-3,h]is -3, find the value of H

Step-by-step explanation:

To find the value of h use the formula for finding the slope of a line

That's

Where ( x1, y1) and (x2 ,y2) are the points

From the question

slope = - 3

The points are [4,-9] and [-3,h]

Substitute these values into the equation

We have

Cross multiply

That's

- 3(-7) = h + 9

21 = h + 9

h = 21 - 9

We have the final answer as

x = 1

step-by-step explanation:

0 ÷ x = 0

0 ÷ 1 = 0
