Answer:
Sara: I can tell from the table that the y-intercept will be the point (0,4) not (-2, 0).
Darrell: Since the b-values go up by 8 each time, I know that the slope of the line has to be 4 not 8.
Step-by-step explanation:
Sara: The y-intercept is when the x value is 0.
Darrell: Slope of the line is 4 because the b-value goes up by 8 each time and the a-value goes up by 2 each time. Slope is [tex]\frac{y}{x}[/tex], so [tex]\frac{8}{2}[/tex], or 4 simplified.
