Professor4x + 8y = 12
Hence
8y = -4x + 12
Divide both sides by '8'
Hence
y = -x/2 + 3/2
This is a straight line with a sloper of '-1/2' and a y-intercept of 3/2 ( 1 1/2 = 1.5)

What is the effect on the graph of the equation y equals x2 plus 1 when it is changed to y equals x2 plus 5?
It keeps the same shape and size, but the whole thing rises four units on the paper, as if by magic.
How can you translate the graph of y equals x to obtain the graph of y equals x-4 plus 2?
y equals x-4 plus 2 is the same as y = x-2. You just translate the graph of y=x, 2 units to the right, OR 2 down.
What equation has the same x intercept as y equals 3x plus 2?
It can be: y = 6x+4
What is an equation for a graph that is parallel to the graph of the equation y equals -0.5x plus 2?
For graphs of parallel lines , the slope is ALWAYS the same, in this case, '-0.5'. However , the constant, '2' in this case, can be any numberyou like. e.g. y = -0.5x + 1,000,000 are parallel lines.
What is the y and x intercept for the equation 3x plus 5y equals -15?
We cannot find out the y and x intercept for the equation 3x plus 5y equals -15 by a single equation . But , we can try a hit and trial method for the same . when x =0 y =-3. when y=0 x=-5.
