Question

Write an equation in slope intercept form of the line that passes through (4, 1) and (5, -1).

Answer 1

Do you have a graphing calculator?

Answer 2

No, that's why I'm asking these questions.

Answer 3

You can download one from the internet.
Easy peasy.

Answer 4

I'm not using my own computer right now.

Answer 5

first we have to find our slope, m
m= -1-1/5-4=-2

Answer 6

next we substitute m into our slope intercept equation
y=-2x+b
and plug in one of the given coordinates (5,-1)
-1=-2(5)+b
-1=-10+b
b=9
therefore our slope intercept equation is y=-2x+9 :]
