Question

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 ).

Answer 1

Gradient of the line formed;
m=
`(change in y)/(change in x)`
m=
`(-2-1)/(6--5)`
m=
`(-3)/(11)`
y=mx+c
y=
`(-3)/(11) x+c`
Replacing for x and y;
1=-3/11*(-5)+c
1=15/11+c
c=1-15/11
c=-4/11
y=
`(-3)/(11) x- (4)/(11)`
