Question

How do you find the slope and intercept to graph `x+y=7`?

Answer 1

Write the equation in the form of `y=mx+c` ,where, `m` is the slope and `c` is the intercept of `Y` axis.

So,given equation is, `x+y=7`

arranging it we get, `y=-x+7`

So,slope is `-1` and intercept is `7` graph{x+y=7 [-22.8, 22.81, -11.4, 11.4]}

click on the graph,where it touches `Y` axis to see the intercept value.
