A:
Answer:see explanationStep-by-step explanation:The equation of a line in slope- intercept form isy = mx + c ( m is the slope and c the y- intercept )(1)Calculate m using the slope formulam = (yβ‚‚ - y₁ ) / (xβ‚‚ - x₁ )with (x₁, y₁ ) = (0, - 5) and (xβ‚‚, yβ‚‚ ) = (3, - 1) ← 2 points on the linem = [tex]\frac{-1+5}{3-0}[/tex] = [tex]\frac{4}{3}[/tex]Note the line crosses the y- axis at (0, - 5) β‡’ c = - 5y = [tex]\frac{4}{3}[/tex] x - 5 ← equation in slope- intercept form---------------------------------------------------------------------------------(2)using the slope formulawith (x₁, y₁ ) = (- 5, 4) and (xβ‚‚, yβ‚‚ ) = (1, - 2) ← 2 points on the linem = [tex]\frac{-2-4}{1+5}[/tex] = [tex]\frac{-6}{6}[/tex] = - 1Note the line crosses the y- axis at (0, - 1) β‡’ c = - 1y = - x - 1 ← equation in slope- intercept form
