Answer:
Pat a) The graph in the attached figure
Part b)
The slope is
The y-coordinate of the y-intercept is
Step-by-step explanation:
Part a) Which line represents the linear equation ?
To graph the linear equation find the intercepts
we know that
The y-intercept is the value of y when the value of x is equal to zero
so
For x=0
The y-intercept is the point
The x-intercept is the value of x when the value of y is equal to zero
so
For y=0
The x-intercept is the point
Plot the intercepts to graph the linear equation
see the attached figure
Part b) Rewritten in slope-intercept form
we know that
The equation of the line into slope intercept form is equal to
where
m is the slope
b is the y-coordinate of the y-intercept
we have
convert to slope intercept form
isolate the variable y
The slope is
The y-coordinate of the y-intercept is
