Can y’all help me out plz :0

Step-by-step explanation:

First Step: We are simplifying the left-hand side by multiplying the coefficient to the (2x + 9)

Second Step: We subtract 30x from both sides to get all the x's on one side

Third Step: We add (or subtract in this case) like terms, which in this case you're taking 30x from 150x

Fourth Step: You subtract the remaining constant (675) from both sides to isolate your variable (x) on one side

Fifth and Final Step: You divide both sides by x's coefficient, 120, to get the value of x by its self

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

it’s the first one your welcome
