Question

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).

Answer 1

A: If the red line has slope m_₁, then your line is

y-5 = m_₁(x-3)

B: If the blue line has slope m_₂ then your line is

y = (-1/m_₂)(x+4)

So, use the needed slopes, and massage the equations into the form

y = mx+b

Answer 2

0.6 in indicated form
