You can put this solution on YOUR website! A commonly used format for linear equations is the slope-intercept form. It is given by
the equation:
.
.
in which m (the multiplier of the x term) is the slope of the graph and b is the y-intercept
which is the value of y where the graph crosses the y-axis.
.
In your problem you are given the equation:
.
.
By comparing this equation with the slope-intercept form, you can see that the multiplier
of x in the slope-intercept equation is and in the problem you were given it is .
That means that which is the slope must be equal to
.
Then you can look at the constant in the equation you were given. That constant is +3,
and this compares to the + b (the y-intercept) in the slope-intercept equation.
.
Therefore, you can say that the y-intercept is +3.
.
In summary, the slope is and the y-intercept is for the graph.
.
Hope this helps you to work your way through the problem.
