snowflake0531:

First show me a graph of what it looks like

iuytyuioiuytyuiop:

there isnt a graph

snowflake0531:

Graph it on desmos

iuytyuioiuytyuiop:

alright i did

snowflake0531:

Okay, so now, mark up the two coordinate points where xis equal to 3 and x is equal to 7

iuytyuioiuytyuiop:

alright

snowflake0531:

And can you tell me the two coordinate points?

iuytyuioiuytyuiop:

im not sure

iuytyuioiuytyuiop:

3 and 7?

snowflake0531:

Yes, but find the two points, where x is equal to 3 and 7 can you tell me what the y values of those are?

iuytyuioiuytyuiop:

i had a different graph but i changed it

iuytyuioiuytyuiop:

-27 and -175

snowflake0531:

Yep So the two points are (3,27) and (7,-175) Can you find the slope between them?

iuytyuioiuytyuiop:

subtract?

snowflake0531:

Do you know the slope formula?

iuytyuioiuytyuiop:

-27-3?

snowflake0531:

First, let's to y What is -175-(-27)

iuytyuioiuytyuiop:

-200

snowflake0531:

What is -175+27....

iuytyuioiuytyuiop:

202

snowflake0531:

`-175+27` put it into your calculator

iuytyuioiuytyuiop:

-148

snowflake0531:

Okay, and what is 7-3

iuytyuioiuytyuiop:

4

snowflake0531:

What is -148/4

iuytyuioiuytyuiop:

-37
