SHORT ANSWER

A) Write the equation in standard form for the line that passes through the points ( - 5, 1 ) and ( 6, -2 ).

B) Write the equation in standard form for the line that passes through the points ( 4, -2 ) and ( 4, 8 ).

Respuesta :

Gradient of the line formed;
m=[tex] \frac{change in y}{change in x} [/tex]
m=[tex] \frac{-2-1}{6--5} [/tex]
m=[tex] \frac{-3}{11} [/tex]
y=mx+c
y=[tex] \frac{-3}{11} x+c[/tex]
Replacing for x and y;
1=-3/11*(-5)+c
1=15/11+c
c=1-15/11
c=-4/11
y=[tex] \frac{-3}{11} x- \frac{4}{11} [/tex]
