I had an assignment containing 45 problems, and I am unsure of 4, can you check and see if the answers are correct?
1. Write an equation of the line containing the given point and parallel line
My answer was: y=3/7x-22/7
2. Find the equation of the line having the given slope and containing the given point: m=-6,(7,8)
My answer: y=-6x+50
3. Find the slope-intercept of the line that has the given characteristics: slope 8 and y intercept (0,7)My answer was y=8x-7
4. Find an equation of the line containing the given pair of points:(-5,-1)(-9,-7)
I got: y=3/2x-14/5
