Which of these pairs of points
defines a line with a slope ?
A) (0, 4) and (7,5)
B) (4, 0) and (7,5)
C) (4, 0) and (5, 7)
D) (0, 4) and (5, 7)

Respuesta :

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)

Step-by-step explanation:

we know that

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

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

Calculate the slope of each case

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

substitute in the formula

[tex]m=\frac{5-4}{7-0}[/tex]

[tex]m=\frac{1}{7}[/tex]

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

substitute in the formula

[tex]m=\frac{5-0}{7-4}[/tex]

[tex]m=\frac{5}{3}[/tex]

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

substitute in the formula

[tex]m=\frac{7-0}{5-4}[/tex]

[tex]m=\frac{7}{1}=7[/tex]

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

substitute in the formula

[tex]m=\frac{7-4}{5-0}[/tex]

[tex]m=\frac{3}{5}[/tex]

Answer:

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