What is the slope and y-intercept of this equation?
2x+4y=14

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 .

As you know john locke said he wanted life liberty and the pursuit of happiness so thomas jefferson was inspired about what john locke said so thomas jefferson wrote the declaration of independence for people to be free for people to be happy
