Answer:
y = - [tex]\frac{2}{5}[/tex] x + 5
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 ) = (5, 3) and (x₂, y₂ ) = (10, 1) ← 2 points on the line
m = [tex]\frac{1-3}{10-5}[/tex] = [tex]\frac{-2}{5}[/tex] = - [tex]\frac{2}{5}[/tex]
The line crosses the y- axis at (0, 5) ⇒ c = 5
y = - [tex]\frac{2}{5}[/tex] x + 5 ← equation of line
