Explanation:

Answer:

y = -2x + 10

use the following formula:

y₁ - y = m ( x₁ - x )

using this formula:

\hookrightarrow↪ y₁ - y = m ( x₁ - x )

\hookrightarrow↪ y - -4 = -2 ( x - 7 )

\hookrightarrow↪ y + 4 = -2 ( x - 7 )

\hookrightarrow↪ y = -2x + 14 -4

\hookrightarrow↪ y = -2x10.

Answer:

y = -2x + 10

steps:


\sf y - y_1 = m ( x - x_1)


\rightarrow \sf y - -4 = -2 ( x - 7)


\rightarrow \sf y + 4 = -2 ( x - 7)


\rightarrow \sf y + 4 = -2(x) -2(-7)


\rightarrow \sf y = -2x + 14 - 4


\rightarrow \sf y = -2x + 10
