Suppose the equation is y = mx+c
The slope = m is 4 so y = 4x+c
(-2,1) lies on the line so substitute x=-2, y=1 into the equation of the line.
1 = 4*(-2)+c or 1 = -8+c or c = 9
So the equation is y = 4x + 9

Write an equation in slope-intercept form for the line that passes through the given point and is parallel to the given line (-7,3); x=4
Point: (2, 4) Slope: -3 Equation: y = -3x+10
Assuming the point is (9, -4), the equation is y = -4.
The equation is: y = 4x-22
It is: y-7 = -3(x--3) => y = -3x-2
