Answer:

y = - [tex]\frac{7}{4}[/tex] x - 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 4, 0) and (x₂, y₂ ) = (0, - 7)

m = [tex]\frac{-7-0}{0-(-4)}[/tex] = [tex]\frac{-7}{0+4}[/tex] = - [tex]\frac{7}{4}[/tex]

The line crosses the y- axis at (0, - 7 ) ⇒ c = - 7

y = - [tex]\frac{7}{4}[/tex] x - 7 ← equation of line
