Answer:
Step-by-step explanation:
Assuming the situation can be modelled using a linear equation, then the line must pass through the point (2,54) and (4,100).
To find the equation of this line, we determine the slope using:
Substitute the coordinates of the points:
We use the following formula to find the equation of this line.
We substitute the first point a d slope to get:
Expand the parenthesis to get:
This simplifies to
This is the slope-intercept from.
