Example problem: Name thex and y intercepts for y=-2x + 1

x-intercept 0= -2x +1 y intercept y = -2(0)+1
-1 = -2x
y= 1
0.5 = x
Find the x and y intercepts for y = 8x-4
O x=8, y = 4
x = 0.5, y = -4
O x=2,y=-4
O x= -4, y = 8

Explanation:

for x=8,y=4

4=8x-4

8x=4+4

8x=8

x=1

y=8 (8)-4

y=64-4

y=60

for x=0.5, y= -4

-4=8x-4

8x= -4+4

8x=0

x=0

y=8 (0.5)-4

y=4-4

y=0

for x=2,y=-4

-4=8x-4

8x=4-4

8x=0

x=0

y=8 (2)-4

y=16-4

y=12

for x= -4,y=8

8=8x-4

8x=8+4

8x=12

x=1.5

y=8 (-4)-4

y= -32-4

y= -36
