Answer:

If the slope is 1/7 the points are A) (0, 4) and (7,5)

If the slope is 5/3 the points are B) (4, 0) and (7,5)

If the slope is 7 the points are C) (4, 0) and (5, 7)

If the slope is 3/5 the points are D) (0, 4) and (5, 7)

Explanation:

we know that

The formula to calculate the slope between two points is equal to


m=(y2-y1)/(x2-x1)

Calculate the slope of each case

case A) (0, 4) and (7,5)

substitute in the formula


m=(5-4)/(7-0)


m=(1)/(7)

case B) (4, 0) and (7,5)

substitute in the formula


m=(5-0)/(7-4)


m=(5)/(3)

case C) (4, 0) and (5,7)

substitute in the formula


m=(7-0)/(5-4)


m=(7)/(1)=7

case D) (0,4) and (5,7)

substitute in the formula


m=(7-4)/(5-0)


m=(3)/(5)
