For question 1, find the x- and y-intercept of the line.

negative 10 lower x plus 5 lower y equals 40

To find the x-intercept, we set y = 0 and solve for x.

-10x + 5(0) = 40
-10x = 40
x = 40 / -10
x = -4

Therefore, the x-intercept is -4.

To find the y-intercept, we set x = 0 and solve for y.

-10(0) + 5y = 40
5y = 40
y = 40 / 5
y = 8

Therefore, the y-intercept is 8.
