I need help with solving it

mars1129 [50]

The given equation has a slope of $\frac{-9}{7}$ . Parallel lines have the same slope.

Point-Slope formula: y - y₁ = m(x - x₁) ; where (x₁, y₁) is the point and "m" is slope

y - y₁ = m(x - x₁)

y - (-4) = $\frac{-9}{7}$ (x - 2)

y + 4 = $\frac{-9}{7}$ x + $\frac{18}{7}$

- 4 - $\frac{28}{7}$

y = $\frac{-9}{7}$ x - $\frac{10}{7}$
