for question 1 find the x- and y-intercept of the line.
-10x+5y=40
To find the x-intercept, we must set y equal to zero and solve for x:
-10x + 5(0) = 40
-10x = 40
x = 40 / -10
x = -4
Thus, the x-intercept is (-4, 0).
To find the y-intercept, we must set x equal to zero and solve for y:
-10(0) + 5y = 40
5y = 40
y = 40 / 5
y = 8
Thus, the y-intercept is (0, 8).
