Question

(-1,-9) and (2,21) into an equation

Answer 1

Answer:

y=10x+1

Step-by-step explanation:

subtract $\frac{21}{2} - \frac{-9}{-1}$ to get a slope of 10

insert the slope into the equation with one of the points. 21=10(2)+b

then solve 21=20+b   b=1

place slope and y-intercept ito the equation. y=10x+1
