Answer:
3)B y intercept is -5 which is what the -5 in the equation stands for, the slope is -2 which means 2 up one left (left since slope is negative)
4)C y intercept of -2, slope is 3/4 rise over run which means we go up 3 and right 4 (right sense slope is positive)
5)A y intercept of 1, slope of 7 which means up 7 over 1
