If the gradient of the line joining the points [4,-9]and [-3,h]is -3, find the value of H
1 answer:
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>Hope this helps you

Answer:
Option A is correct.
The length opposite the angle is the vertical distance from the x-axis on the graph
Step-by-step explanation:
Given:
Unit circle is a circle centered at the origin, (0,0) with radius(r) i.,e r= 1.
The angle forms an arc of length S and the x-axis and y-axis divide the coordinate plane and the unit circle as it is centered at (0.0).
Also, the terminal side intersect the circle at (x, y).
Now, to find the value of ,we will use the trigonometric ratios formulas :
For any right angle,
Here, hypotenuse = r =1 and the side opposite the angle is also called the vertical distance from the x-axis.
therefore,
Also, the length opposite the angle is the vertical distance from the x-axis on the graph
