4.) 2(x-1)+3= 2x+1
Distribute the 2, multiply the 2 by x and -1.
2*x= 2x (all you need to do is put 2 in front of x)
2*-1= -2
2x-2+3= 2x+1
Combine like terms.
2x+1=2x+1
Subtract one on both sides.
2x=2x
Divide by 2 into both sides.
x=1
We can check this by plugging it in.
2(1-1)+3= 2(1)+1
2(0)+3= 2+1
0+3=3
3=3 <== this works
I hope this helps!

(0,0) and (4,1)
Find the slope: m = (y2-y1)/(x2-x1) = (1-0)/(4-0) = 1/4
Input m, x1, and y1 into the Point-Slope equation:
y - y1 = m(x - x1)
y - 0 = 1/4 (x - 0)
y = 1/4 x
Move all the terms to the left side and set equal to zero. Then set each factor equal to zero.
