For which equation is (4, 3) a solution?
y = 2x – 1
y = 3x – 4
y = 2x – 5
y = x + 3

Really need on these. i have no idea what to do

What is the solution to this system of equations? y= 2x - 3.5 x - 2y = -14

The point a is at –2 and the point b is at 7. marissa would like to divide this line segment in a 4: 3 ratio, and she would like to use the formula x = (x2 – x1) + x1. what values should she substitute into the formula? a = a + b = x1 = x2 =
