Question

How do I solve this?

Answer 1

for this case with the first table we can find the equation of the line using the following formula for the slope:

`m_1=(y_2-y_1)/(x_2-x_1)=(0-2)/(-1-0)=2`

And the y intercept would be b=2

Then the equation for the first equation is:

y= 2x +2

the second equation is given by:

y= -2x-2

then the best solution would be:

Function 1 has a positive slope and a positive y-intercept. Function2 has a negative slope and a negative y-intercept
