Best ResponseYou've already chosen the best response.0Remember that the equation of a linear function is: y = mx + b Where m is the slope of the line and b is the yintercept.

Best ResponseYou've already chosen the best response.0b is easiest to solve here, it's the yvalue where the line crosses the yaxis. In other words, it's the yvalue of x=0.

Best ResponseYou've already chosen the best response.0The slope of the line is equal to the rise and run between two points. I will choose two points: (0, 110) and (20, 70). The rise is: 70  110 = 40. The run is: 20  0 = 20. Rise/Run gets us: 40/20 = 2. So you are correct.

Best ResponseYou've already chosen the best response.0Sorry, but that is not correct. y = mx + b Simply substitute the variable m for your numeric slope value and replace b with the yintercept :)

Best ResponseYou've already chosen the best response.0The yintercept is where the line crosses the yaxis. Can you see that the line crosses the yaxis at y=110?

Best ResponseYou've already chosen the best response.0Sorry about that. Are you solving for b algebraically? The yintercept (b) is the value of y when x=0. Since we've already found the slope, we have the equation: y = 2x + b, correct? So what is y equal to when our x = 0?

Best ResponseYou've already chosen the best response.0I am sorry if I am being confusing. Let's start over and take it slow. I'm going to assume that you know how to do slope since you did that so well.

Best ResponseYou've already chosen the best response.0You got 2 for the slope value. The slope value is m. In our equation for a line: y = mx + b, we can replace m with the 2 you found for slope.
