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 - yβ ) / (xβ - xβ )with (xβ, yβ ) = (0, - 5) and (xβ, yβ ) = (3, - 1) β 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 β equation in slope- intercept form---------------------------------------------------------------------------------(2)using the slope formulawith (xβ, yβ ) = (- 5, 4) and (xβ, yβ ) = (1, - 2) β 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 β equation in slope- intercept form
