Determine the x-intercept and the y-intercept of each problem.

20x + 8y = 240

15x + 3y = 270

y = 8x + 168

20x + 8y = 240

x-intercept, y = 0; 
20x + 8(0) = 240
20x = 240
x = 240/20
x = 12

y-intercept, x = 0; 
20(0) + 8y = 240
8y =240
y =240/8
y = 30



15x + 3y = 270

x-intercept, y = 0; 
15x + 3(0) = 270
15x = 270
x = 270/15
x = 18

y-intercept, x = 0; 
15(0) + 3y = 270
3y = 270
y = 270/3
y = 90


y = 8x + 168

x-intercept, y = 0; 
0 = 8x + 168
8x = -168
x = -168/8
x = -21

y-intercept, x = 0; 
y = 8(0) + 168
y = 168

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
