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>

What? I don’t know what your saying
Let's call the unknown number ' W '.
You said that 100 is 1 tenth of W .
Write that as an equation: 100 = (1/10) W
Now multiply each side by 10 : (10) 100 = (10) (1/10) W
Left side: (10) 100 is 1,000
Right side: (10) (1/10) is 1
So the equation says that <em>1,000 = W
