Is (2,5) a solution of y=1/2x+4?

To solve this problem, you need to plug the given integers in for the variables in the equation and solve.

So, (2,5) means that x=2 and y=5.

When we put this into the equation, we get (5) = 1/2(2) +4

To simplify this equation, first we should multiply 1/2 by 2.

1/2*2=1, so your equation is now 5=1+4

1+4 =5, so the equation would be 5=5.  This is a true statement, so you know that your ordered pair, (2,5) is a solution of the equation.

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

do you confirm there was a mistake in the question?
