Please help T_T

gunsodo · Answer

Okay, typing...

gunsodo · Answer

First find slope..

gunsodo · Answer

slope = difference of y/ difference of x
so slope will be (-3-4)/(3-(-5)) = -7/8

gunsodo · Answer

Replace slope into the equation,
y = mx + b ---> y = -7/8x+b

gunsodo · Answer

The left is for you to work it out!!
Find b by using the coordinate, a simple equation solving needed

I'm not sure please help walk me through this! @gunsodo

gunsodo · Answer

So, continue lol

mathsucks321 · Answer

I don't know how I have trouble with these

gunsodo · Answer

After we've got y=-7/8 x+b
we input (3,-3) into the equation we've just gotten

mathsucks321 · Answer

How to I input it?

gunsodo · Answer

So, we'll get -3 = -7/8 (3) + b
And b = -3/8
