Write an equation in the indicated form for each statement described below.
(A graph shows two lines intersecting at x=-2 and y= 1 in a tilted X shape)
A. Write an equation in slope-intercept form for the line parallel to the red line and going through the point (3,5).
B. Write an equation in slope-intercept form for the line perpendicular to the blue line and going through the point (-4, 0).
A: If the red line has slope m1, then your line is
y-5 = m1(x-3)
B: If the blue line has slope m2 then your line is
y = (-1/m2)(x+4)
So, use the needed slopes, and massage the equations into the form
y = mx+b
