Answer:
When x is 3, y is 4.5
Step-by-step explanation:
The difference between 4 and 6 is 1.5 and so is 10 and 15,
3 x 1.5 = 4.5
Slope intercept form is y=mx+b
to solve for m (slope) you must first subtract y2-y1 and x2-x1 then divide your answers
-1 - -5 = 4 (y)
2 - 4 = -2 (x)
4/-2 = -2
so your slope is -2
next plug in your slope and the point you choose
-1 = -2(2) + b
or
-5 = -2(5) +b
