Answer:
1. Ox-intercept is -4; y-intercept is 8.
2. Ox-intercept is 16; v-intercept is 20.
Explanation:
1. -10x + 5y = 40
Recall the equation of line in slope - intercept form :
y = mx + c , where m is the slope and c is the y - intercept
Writing the given equation in this form,we have:
-10x + 5y = 40
5y = 10x + 40
y = 10/5 x + 40/5
y = 2x + 8
comparing with y = mx +c , then y - intercept is 8 , the x - intercept is the point at which y = 0 , substituting y = 0 into the equation , we have
0 = 2x + 8
2x = -8
x = -8/2
x = -4
2. Following the same procedure:
y = -5x/4 + 20
y - intercept = 20
x - intercept = 16
