Which graph represents solutions to the equation y=\frac{3}{2}x+1?

What is the slope of the line y=-\frac{3}{4}x-4?

Which of the following statements are true of a line through the points (-\frac{5}{2},-3) and (5,2)? Select all that apply.

The line intsects the y-axis at (0,-\frac{3}{2})

The slope of the line is \frac{3}{2}

The line intersects the x-axis at (2,0)

An equation for the line is y=\frac{2}{3}x-\frac{4}{3}

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
