Question

I am struggling!! Help!!

Answer 1

`y= 9/4x+5`

Explanation:

I'll go over #7 and you should be able to do the rest.

Slope intercept form general equation is:

y = mx + b

I bolded the value you need to change/find.

m is the slope

b is the y-intercept

You can calculate m using:

`m=(y_2-y_1)/(x_2-x_1)`

you're given (-4,-4) and (0,5) so y₂=5, y₁=-4, x₂=0, x₁=-4

`m=(5-(-4))/(0-(-4))=9/4`

Plug your value into the point-slope formula.

`y = m(x-x_1)+y_1`

`y = (9/4)(x-(-4))+(-4)` simplify it

`y= 9/4x+5` the simplified form is the slope-intercept formula
