Category 2 Example 1 - no calculation required
The slope and the y-coordinate of the y-intercept are given (a point with x = 0 is the y-intercept). Match them to the answer choices given as y = mx + b equation.
Category 2 Example 3 - no calculation required
The slope can be determined from the graph as rise/run. The y-intercept can be directly read from the graph. Match them to the answer choices given as y = mx + b equation.
Category 3 Example 1 - mental math
It can be read from the equation as C/B.
Category 3 Example 2 - mental math
The slope can be determined from the graph as rise/run. Match this with -A/B in each answer choice and eliminate the answer choices where the slope does not match.
The y-intercept can be read from the graph. Match it with C/B in the remaining answer choices.
Category 8 Example 1 - no calculation required
Use the transformation rule given in Key Points for left shift and match it with the answer choices.
Category 8 Example 2 - no calculation required
Match the reflected graph based on the transformation rule given in Key Points.
