The slope-intercept form:

m - slope
b - y-intercept
We have the slope
.
Put the coordinates of the point (-1, 5) to the equation of the line:

<em>add 2 to both sides</em>

14) The answer is a) y = 2x. 2 is the slope and the line does not cross over the Y axis in this picture so there is not a Y-intercept you can see.
15) You pretty much just estimate. On the graph when you find 50 minutes and go up its around 140. 50 x 2 is 100 minutes. so just multiply 140 by 2 and its 280 so just round to the closest one.
