Problem 2 Got It? What is the equation of a line with m = 6 and y-intercept (0, 5)?

y = 5x + 6

y = 6x + 5

y = 5

y = 6x

Problem 2 Got It? Reasoning: In the previous item, do you get a different equation if you use (-6, 0) and the y-intercept to find the slope of the line? Explain.

Yes; choosing different points results in a different slope.

No; any two points on a line can be used to calculate the slope.
