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.
1 1/3 + 5 2/9 = first find the lowest common denominator = 9
1 3/9 + 5 2/9 = 6 5/9
Answer:
-7 = y
Step-by-step explanation:
3x=y-5
Let x = -4
3(-4) = y-5
-12 = y-5
Add 5 to each side
-12 +5 = y-5+5
-7 = y
