## mady625 3 years ago Write an equation in slope-intercept form for the line passing through (5, 1) and (-4, 7)

1. Romero

y-y1=m(x-x1)

2. ParthKohli

Standard form is y = mx + b First determine the slope. $$\Large \color{Black}{\Rightarrow {Slope = {y_2 - y_1 \over x_2 - x_1}} }$$ Then substitute m with the slope and find b.

3. Romero

where (x1,y1) are a point in the line. You are given two

4. Thatsmeh

I agree with ParthKohli i am new so he typed it in faster XD

5. Romero

choose 1 and then find the slope (m) with the given equation from Parthkohli

6. Romero

But it's better to do it from point slope form and then isolate y. slope-intercept form is sometimes hard to see right away and you are not given the y-int as one of the points

Option A: y=-2/3x+13/3 Option B: y=-2/3x-13/3 Option C: y=2/3x-13/3 Option D: y=2/3x+13/3

Umm you might want give it a try first....we already told you how to do it. Don't be lazy

I tried and got the first answer

is the first answer correct?

11. Romero

yup

12. Romero

Good job!
