If <span>y = –4x – 7, the x-intercept is found by setting y=0 and solving for x:
</span><span>0 = –4x – 7 => 4x = -7, or x = -7/4 The x-intercept is (-7/4, 0).
</span><span>The y-intercept is found by setting x = 0 and reading off the value of y:
y = –4x – 7 => y = 0 - 7, or y = -7. The y-intercept is (0, -7).</span>
A-3b=9
a=b-3
b-3-3b=9
-2b-3=9
-2b=12
2b=-12
b=-6
a=-6-3
a=-9
Solution: (-9,-6)
----
Check:
-9=-6-3
-9=-9
TRUE
