Thisssss oneeeeee :)?????
SCORPION-xisa [38]

Answer:

y = 3x - 5

Step-by-step explanation:

I used my calculator so that it would be faster.

But if you want work you have to find the slope then plug in.

To find the slope use points (1, -2) and (2, 1) use this formula \frac{y2 - y1}{x2 - x1}

Plug the points in \frac{1 - -2}{2-1} =\frac{3}{1} = 3

So your slope is 3

NOw Plug In (1, -2)

-2 = 3(1) + b (b represents the y- intercept)

-2 = 3 + b (subtract 3 on both sides)

-5 = b

The final equation is y = 3x - 5

Hope this helps ya!!
