The general form of an equation is 
. Solving for (5+X)(5-X)=7 by multiplying the factors and subtratcting 7 on both sides gives the equation 
, so
A = 1
B = 0
C = -18
A = 1
B = 0
C = -18
Explain why 7 times x/7 equal x. how does this relate to solving division equation

Answer: The equation is y = 4x+3
Slope = 4
y intercept = 3
========================================================
Explanation:
Let's start off by finding the slope.
The slope is 4.
The y intercept is 3 because of the point (0,3)
We go from y = mx+b to y = 4x+3
m = slope
b = y intercept
---------------
Check:
Plug in x = 0 and we should get to y = 3
y = 4x+3
y = 4(0)+3
y = 0+3
y = 3
That works out. Now try x = 4. It should lead to y = 19
y = 4x+3
y = 4(4)+3
y = 16+3
y = 19
The answer is confirmed.
