Question 409317: graph 2x-7=14 using the intercepts

For the x-intercept, we should separate the x-coefficient from the whole numbers.
REMEMBER: When finding the "x-intercept," y is always equal to 0.
2x+-+7+=+14
2x+=+14+%2B+7
2x+=+21
x+=+21%2F2
x+=+%2821%2F2%29+or+10.5
The x-intercept then occurs at (10.5, 0).
For me, finding the slope of a line is way easier than solving for (x,y) for the plotting of points. The slope is always the numerical coefficient of x when y is on the other side of the equation. Like here:
y+=+2x+-+7+-14
y+=+2x+-+21
The slope is 2 or 2/1 in fraction, which means a rise of 2 (up) and a run of 1 (right) for every point.
