Question

If line 1 passes through (2, -6) and (-2, -2) and line 2 passes through (-3, 2) and (2, 12), where will line 1 and line 2 intersect?

a)(-4,0)
b)(-2,-3)
c)(-6,2)
d) (-2,-2)

Answer 1

a) (-4, 0); Find the slope of each set of points. Set up both equations, using the slope for each, in the form
y = mx + b. Insert each slope. Use a point from each equation to determine the y-int for each (-4 and 8, respectively). Solve using systems of equations.
