Question

please help what is the equation

Answer 1

let us take any two points here (5,20) and (7,30)

now let us use slope formula to get its slope

$slope=\frac{y2-y1}{x2-x1}$

$slope=\frac{30-20}{7-5}$

slope =5

now let us use one coordinate (say (5,20)) and slope to get the y intercept

20= 5*5 +b

b=-5

plugging the values of b and m in the given equation we get

y=5x-5

or c=5m-5
