Answer:
Option D)
The items have same y-intercepts and different rates of change.
Explanation:
y = mx + c
is the equation of straight line
here m is the gradient and c is the y intercept
First equation given in the question:
y = 1.5x + 3.5
Construction of second equation
m = y2-y1 / x2 - x1
= 2.5 - 1.5 / -1+2
= 1
y = mx + c
1.5 = (-2) + c
c = 3.5
So the second equation will be
y = x + 3.5
