slope: 0.8, y-intercept: 10
a.
y = –0.8x + 10
c.
y = 0.8x + 10
b.
y = 0.8x – 10
d.
y = 5/7x + 10 **Weegy:** (8x ? 2) + (7x + 6) = 15x + 4 (More)

If y = –48 when x = –8, find y when x = –3.
a.
y = 6x; –18
c.
y = 6x; –21
b.
y = 5x; –18
d.
y = –6x; 18 User: y = 1/3x + 9
3x – 9y = 4
a.
No, since the slopes are different.
b.
No, since the y-intercepts are different.
c.
Yes, since the slope are the same and the y-intercepts are the same.
d.
Yes, since the slope are the same and the y-intercepts are different.

The lines for y = 1/3x + 9 and 3x – 9y = 4 are parallel since the slope are the same and the y-intercepts are different.
