Explanation:
10x + 8y = -40 y and x intercept
y intercept occurs when x = 0
10(0) + 8y = -40
8y = -40
divide both sides by 8:
8y/8 = -40/8
y = -5
( 0 , -5 )
_______________________________
x intercept occurs when y = 0
10x + 8(0) = -40
10x = -40
divide both sides by 10:
10x/10 = 040/10
x = -4
( -4 , 0 )
