Step-by-step explanation:
A is 540
B is 30
C is 720
D is 360
Answer: C
Step-by-step explanation:
The slope of the given line in the image is -4 , Option A is the answer.
<h3>What is the equation of a straight line ?</h3>
The equation of the straight line is given by
y =mx +c ,
Where m is the slope , C is the intercept
The line is passing through the point
(-1,8) ,(2,-4)
The slope is given by
m = (y₂-y₁) /(x₂-x₁)
m = (-4 - 8 )/(2 +1)
m = -12/3
m = -4
Therefore the slope of the given line in the image is -4 , Option A is the answer.
