Oliver and Marie are graphing two equations on a coordinate grid. Oliver has graphed the equation y = 2x + 2. If Marie graphs y
2 answers:
Answer:
B) 5 units lower.
Step-by-step explanation:
We have been given that Oliver has graphed the equation and Marie graphs
. We are asked to find where Marie's graph will be with relation to Oliver's graph.
We can see that both lines are in slope-intercept form of equation: , where,
m = Slope of the line,
b = Initial value or y-intercept.
We can see that both lines have same slope, but y-intercepts for both lines are different.
Since y-intercept is the point, where line crosses y-axis. We can see that Oliver's line will cross y-axis at y=2, while Marie's line crosses y-axis at y=-3.
Since -3 is 5 units below from 2, therefore, y-intercept of Marie's graph be 5 units lower than Oliver's graph and option B is the correct choice.
