Answer:
<h2>h = 12</h2>
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
<h3>h = 12</h3>
