Answer:
y = 1
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to [tex]\frac{1}{7}[/tex]
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (7, 2) and (x₂, y₂ ) = (0, y)
m = [tex]\frac{y-2}{0-7}[/tex], that is
[tex]\frac{y-2}{-7}[/tex] = [tex]\frac{1}{7}[/tex] ( cross- multiply )
7(y - 2) = - 7 ( divide both sides by 7 )
y - 2 = - 1 ( add 2 to both sides )
y = 1
