number 43 and work please!

Answer 1

Look below

Explanation:

The equation is y=mx+b where m is the slope and b is the y-intercept.

We can find this by first calculating the slope by using any two x and y values

`Slope = (rise)/(run) = (y_(2)-y_(1))/(x_(2)-x_(1) ) = (-12+2)/(3-1) =(-10)/(2) =-5`

Now we can plug the slope back into the equation to solve for the y-intercept

y=-5x+b

-12=-5(3)+b

-12=-15+b

b=3

Therefore the equation is y=-5x+3

Now we plug in the values for x/y to complete the table

y=-5(0)+3=0+3=3

y=-5(2)+3=-10+3=-7

68=-5x+3

65=-5x

x=-13

y=-5(25)+3=-125+3=-122

So the missing values (in order from left to right) are:

3, -7, -13, and -122
