Aline passes through the point (-2,7) and had a slope of -5 what is the value of a if the point (a,2) is also on the line -7 -1 1 7

a = - 1

Step-by-step explanation:

Calculate the slope m using the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 2, 7) and (x₂, y₂ ) = (a, 2)

m = = = - 5

multiply both sides by (a + 2)

- 5 = - 5(a + 2) ( divide both sides by - 5 )

1 = a + 2 ⇒ a = 1 - 2 = - 1

22.83 repeating

step-by-step explanation:

137 ÷ 6 is 22.8333333 therefore we understand that 3 is repeating.
