so my professor gave us this assignment and I'm having hard time doing it and this is all the questions no missing information or anything else, that was all that was given to us. And also we're dealing with slope, equations of line, and slope of line in linear Algebra, so you can have an idea of what you're dealing with.

Find the equation of the lines given the information in the problem. 1. With a slope of - = and the point (0, 7). 2. With a slope of 4 and the point (-3, 1). 3. With the points (-2, -5) and (4, -13). 4. A. What is the slope of the line between these points? Gallons Mileage 5 10520 12 10675 B. What does it represent in the problem? C. Write the equation of the line. 5. A 3-lb box of candy costs $27 and a 5-lb box of candy costs $46.50. A. What is the slope of the line between these points? B. Explain the meaning of the slope in terms of cost and pounds in a complete sentence. C. Write the equation of the line. D. Use the equation to determine the price of a 8-lb box of candy
