Question

I'm having trouble finding the equation of the line through the given points : (-1,8) & (3, -4). Thanks in advance!! :)

Answer 1

First try to get the slope of the line, using the formula: \[m=\frac{y_2-y_1}{x_2-x_1}\]

Answer 2

I'm getting -3

Answer 3

Did you get the equation?
You use
\[y-y_{1}= m(x-x_{1})\]
and then use algebra to re-arrange into the form
y = mx + b
