1 answer:
Answer:
y = 15x + 50
Step-by-step explanation:
We set out by finding the slope
the two points give are (15,275) and (25,425)
Slope m is;
y2-y1/x2-x1 = (425-275)/25-15 = 150/10 = 15
So the equation is like;
y = 15x + b
To get b, let us use the point (15,275)
We have
275 = 15(15) + b
b = 275-225
b = 50
So the equation is;
y = 15x + 50
