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
