Question

Find the missing value so that the two points have a slope of 1/7 (7,2) and (0,y)

Answer 1

Answer:

y = 1

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to $\frac{1}{7}$

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (7, 2) and (x₂, y₂ ) = (0, y)

m = $\frac{y-2}{0-7}$, that is

$\frac{y-2}{-7}$ = $\frac{1}{7}$ ( cross-  multiply )

7(y - 2) = - 7 ( divide both sides by 7 )

y - 2 = - 1 ( add 2 to both sides )

y = 1
