Question

Write the slope-intercept for of an equation of the line that passes through the given point and is parallel to the graph of each equation.

(1,-3), y = -4x - 1

Please help, explain.

Answer 1

The equation for one line is shown. You have to write the equation of another line that has the same slope as that first line and goes through (1,-3). First, what's the slope of that first line? That will be the slope for the line you need. Then, just start writing that equation, with unknown "x" and "y" values, then put in the values 1 and -3 for slope and solve for the intercept. There, you now have the slope and the intercept for the second line. If all these instructions don't make sense (it's a lot!), just try to answer the first question, of what's the slope of the line whose equation is given? Then I can help you through the other steps bit by bit. OK?
