just use the equation of y = mx + b. m is your slope and b is the y-intercept.

plug in your known factors…

(-13) = (-3)(7) + b

then just solve for b and you’ll get b = 8.

now just rewrite your equation and you’ll get your line.

y = -3x + 8

There is an equation you can use for this.

y-y1=m(x-x1)

you fill in -13 for y1, 7 for x1, and -3 (the slope) for m.

y-(-13)=(-3)(x-(7))

then solve for y.
