For question 1, find the x- and y-intetcept of the line.
-10x+5y=40
A. x-intercept is 5; y-intercept is - 10
B. x-intercept is 8; y-intercept is -4
C. x-intercept is -10; y-inercept is 5.
D. x-intercept is -4; y-intercept is 8
To find the x-intercept, we set y equal to 0 and solve for x:
-10x + 5(0) = 40
-10x = 40
Dividing both sides by -10 gives us:
x = -4
So the x-intercept is -4.
To find the y-intercept, we set x equal to 0 and solve for y:
-10(0) + 5y = 40
5y = 40
Dividing both sides by 5 gives us:
y = 8
So the y-intercept is 8.
Therefore, the correct answer is D. x-intercept is -4; y-intercept is 8.
