L1: (-2,-1), (1,5) L2: (3,5), (5,9) These lines are parallel because they have the same slope but different y-intercepts.(Is this true and if it is how do you solve the problem and graph it)

Answer 1

Find the slope and y intercept of each, and compare.

m = (y1-y2)/(x1-x2) to find the slope.

y - y1 = m(x-x1) to write the line in slope-intercept form.
