Answer:

y = 4x + 5

To find the slope do :

                                                <u>21 - (-3)</u>

                                                 4 -(-2)

That will equal :

                                 <u>24</u>             simplified :     4

                                  6

Take your slope and one of the points and plug it into y = mx + b

That will look like:   (21) = 4(4) + b

                                  21 = 16 + b

Subtract 16                <u>-16  -16      </u>

on both sides

This is your y-int:       5 = b

Put the slope and y-int into the equation

And this is your answer:   y = 4x + 5

9. Lines A and B are parallel lines. Find the measures of angles 1, 2 and 3. ​
Reika [66]

Answer:

<1 = 33

<2 = 90

<3 = 57

Step-by-step explanation:

<3 = 57 because of alternate interior angles

<2 + <3 + 33 = 180

<2 + 57 + 33 = 180

<2 + 90 = 180

<2 = 90

<1 + <2 + 57 = 180

<1 + 90 + 57 = 180

<1 + 147 = 180

<1 = 33
