OpenStudy (anonymous):

"What is the slope of a line that passes through the point (−1, 1) and is parallel to a line that passes through (4, 6) and (−1, −4)?" Please explain how to do this! I want to understand the process

OpenStudy (abb0t):

slope = m = \(\frac{y_2-y_1}{x_2-x_1}\)

OpenStudy (anonymous):

Oh alright...so that makes the slope 2? Is that the answer, or whats the next step
