Write an equation given the a table

6. -4x+3   7. 2x+24   8. 4x+3

Step-by-step explanation:

The formula to find slope is y2-y1/x2-x1.  With y2 serving as any y value on the table that is not whatever you decide as your y1 value, same goes for the x values.

y2 and x2 should be from the same line in the table, same goes for x values.

Explaining #6: I used point (2,-5) and (1,-1).

y2=-5, y1=-1, x2=2, x1=1

Plug values into slop equation--> (-5-(-1)/(2-1)= -4

To find the y-intercept you would either take the formula y=mx+b and plug in a point from the table and slop you just found to find b. Or when x=0 on the table the y value is your b/y-intercept.

Hope this helped and you can understand!

what i would say the best answer is a. 40.5
