An Algebra student answers homework problems at a rate of \frac{1}{4} of a problem every minute. After working for an entire hour, she finially finishes her assignment. A graph shows the number of problems she had left to do, y, after x minutes of work. What is the y-intercept of the graph, and what does it represent?

(4,0); the number of minutes she spends solving each problem

(0,60); the total time it takes her to finish the assignment

(0,15); the total number of problems in the assignment

(1,4); the ratio of problems completed to minutes passed

Select the slope-intercept form equation for a line with a y-intercept of 30 and a slope of -25.

y=-25x+30

y=30x-25

y=-30x+25

y=25x-30
