Which equation represents a line that passes through (-2, 4) and has a slope of 2/5

Respuesta :

Answer:

see explanation

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 )

Here m = [tex]\frac{2}{5}[/tex], thus

y = [tex]\frac{2}{5}[/tex] x + c ← is the partial equation

To find c substitute (- 2, 4) into the partial equation

4 = - [tex]\frac{4}{5}[/tex] + c ⇒ c = 4 + [tex]\frac{4}{5}[/tex] = [tex]\frac{24}{5}[/tex]

y = [tex]\frac{2}{5}[/tex] x + [tex]\frac{24}{5}[/tex] ← equation of line
