Equations don't have slopes or y-intercepts, but their graphs might.
Let's solve this equation for 'y', and see whether its graph has them.
2x + 4y = 14
Subtract 2x from each side: 4y = -2x + 14
Divide each side by 4 : y = -1/2x + 7/2 .
In this form, we can look at the equation, and see immediately that
if we were to draw its graph, then the graph would be a straight line
with slope= -1/2 and y-intercept= 7/2 .
