The equation is y=mx+c where m is the gradient and c is the y-intercept
I think it's 21% when rounded to a whole number
Download photo math for equations like this, it will also give you it step by step :)
Answer: Slope is 1 because if we have x by itself, we assume it is only one.
y-intercept because according to the slope intercept formula, (y=mx+b), it is in the correct spot.
