Answer:

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
