Answer 2

Answer:

$y= 9/4x+5$

Step-by-step 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:

$m=\frac{y_2-y_1}{x_2-x_1}$

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

$m=\frac{5-(-4)}{0-(-4)}=9/4$

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
