Find the slope and y-intercept for the graph of each equation:

y=x-7 how would you solve this type of equation? i know that with an equation like: y=2x+4 that it would be m=2/1 and b=4. but how would you solve the first one.

If the equation of the line is given in the form :

y = m x + b

then m is the slope.

In this case slope = 1

A y-intercept is a point on the graph where x is zero.

y = x - 7

for x = 0

y = 0 - 7

y = - 7

y-intercept = - 7

When page be open in rectangle type:

y = x-7

and click option =

After few seconds you will see graph.
