Given the equation y − 4 =3/4 (x + 8) in point-slope form, identify the equation of the same line in standard form.

−x + y = 10

3x − 4y = −40

y = x + 12

y = x + 10

Question

Given the equation y − 4 =3/4 (x + 8) in point-slope form, identify the equation of the same line in standard form. 

 −x + y = 10 

 3x − 4y = −40 

 y = x + 12 

 y = x + 10

do you know what standard form is?

anonymous · Answer

Ax + By = C

anonymous · Answer

that knocks out the last two
also, the A can never be negative, so you're left with choice 2

anonymous · Answer

also, to get the equation in standard form, distribute the 3/4 and move the x to the same side as the y
then, multiply the whole equation by 4 and -1 to get rid of the denominator and the negative sign in front of the x
