Solve the system of equations by graphing
y = 6
y = 3x - 3

x=3, See the graph below

Step-by-step explanation:

SINCE THE QUESTION ASK FOR GRAPHING

See the graph below

-------------------------------------------------------------------

I AM ALSO GOING TO SHOW A SECOND WAY WITHOUT GRAPH FOR EXTRA

Given

y=6

y=3x-3

Use substitution (Substituting the value of y)

3x-3=6

Add 3 on both sides

3x-3+3=6+3

3x=9

Divide 3 on both sides

3x/3=9/3

x=3

Hope this helps!! :)

Please let me know if you have any questions

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?
