Find an equation of the line that passes through the given points. (-2, -1) and (7, -4)
y=-1/3x-7. Use the formula y=mx+b, where "m" is slope and "b" is your y-intercept. Slope is rise/run, or (y2-y1)/(x2-x1), which is (-4--1)/(7--2), which equals -3/9, which can be simplified into -1/3. Then draw the line (or plug a coordinate into the formula) and find the y-intercept.
