Question

Which is the equation to the line passing through points (2, –7) and (5, –1)?

Answer 1

first find the slope, you know the slope formula?

Answer 2

if you could instruct just a little id appriciate it...

Answer 3

\[slope=\frac{y-y_1}{x-x_1}\]
\[slope=\frac{-1-(-7)}{5-2}\]

Answer 4

and would that be the final answer?

Answer 5

so, you'll get 2 for slope,
then use
y-y1=m(x-x1) pick any points (2,-7)
y-(-7)=2(x-2)
y+7=2x-4
add both sides by -7 and you're done

Answer 6

so add 7 to the one above?

Answer 7

no , add -7

Answer 8

oh ok thanks so much!

Answer 9

welcome!
