• +3
• -4
• +7
• -7
• -3
• 4

Answer explanation

The original equation is

y-y₁=m(x-x₁)

You have to remember that 2 negatives make a positive so both -3 and -7 become positive when plugged into the equation.

Answer explanation

The slope is 3 and the

y-intercept is (0,-4)

Plot the y intercept then use the slope to go up 3 and right 1 from the point plotted.

This point now is (1, -1)
