Why is the 7 important in this equation? y=3x+7

1) it is the slope
2) it is the golden number
3) it is the y-intercept
4) it is the x-intercept

Step-by-step explanation:

The line is in slope-intercept form:

y=mx+b

where m is the slope and b is the y-intercept.

We are given the equation:

y=3x+7

If we compare the two equations, we see that m and 3 correspond, while 7 and b correspond.

This means that the slope is 3 and the y-intercept is 7. So, the correct answer is 3. It is the y-intercept

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
