Simplify −2xy + 3x − 2xy + 3x
a. 2xy
b. 4xy +6x
c. 4xy − 6x
d. −4xy + 6x

The correct answer is option D.  -4xy + 6x

Step-by-step explanation:

It is given an expression, −2xy + 3x − 2xy + 3x  

To simplify the given expression

Let the expression be −2xy + 3x − 2xy + 3x

−2xy + 3x − 2xy + 3x   = -2xy - 2xy + 3x + 3x     [write similar terms together]

 = -4xy + 6x

Therefore the correct answer is option D.

-4xy + 6x

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

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
