algebra the slope- intercept form
posted by Alie Mae on .
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
For graph :

When page be open in rectangle type:
y = x-7
and click option =
After few seconds you will see graph.
