Question

Help me through this! Giving medal! What is the equation in point-slope form of the line passing through (–1, 3) and (1, 7)?

Answer 1

First, use the slope formula:
\(\huge \frac{y_2-y_1}{x_2-x_1}\)

Answer 2

With points on the line \(\large (x_1,y_1)\) and \(\large (x_2, y_2)\)

Answer 3

7-3
---
1-(-1)

4/2
Slope is 2

Answer 4

nice job. Now plug what you know into the point-slope formula for the equation of a line

\(\large y-y_1=m(x-x_1)\) where m = slope

Answer 5

y-7 = 2(x-1)

Answer 6

So is that the answer?

Answer 7

yes point slope format of the equation of a line
