Tucker Hoover · Answer 1

y=25x+7

Step-by-step explanation:

The equation will be in the form of y=mx+c where m is gradient/slope and c is constant,

normally referred as y intercept.

Slope is given by dividing change in y by change in x

Slope = (57-32) / (2-1) = 25

Therefore slope is 25

For the first term

32=25 (1) + c

C=32-25=7

Therefore, the general equation will be y=25x+7
