Spring 2025 Final Exam Review

The conversion of degrees Celsius to degrees Fahrenheit can be represented by a linear relationship. The graph shows the linear relationship between y, the temperature in degrees Fahrenheit, and x, the temperature in degrees Celsius from the freezing point of water.

Which equation best represents this situation?

Answer explanation

Plug each equation into Desmos and see which one matches.

Since C and D both have a y-intercept of 32, then you have to find another point on the graph to see if it matches.

I chose to put the point (40,104) because it's another good point on the graph, so you type the point in Desmos with ( )

Answer choice C is that one that has the matching y-intercept and second point

Answer explanation

1. Plug in y = left side of equal sign in box 1 (change w's to x's)

2. Plug in y = right side of equal sign in box 2 (change w's to x's)

3. Find where the lines intersect and the solution is the x-value of the point (x, y)

Write the equation of the line that passes through the points
(3, 3) and (4, -1).

• y = -4x - 15
• y = 1/4x + 15
