Answer:
9.42
Step-by-step explanation:
1.5 is the radius so you plug it into 
to get about 7.07 than do get the volume of a sphere you multipy by (4/3). I used my phone so you may want to use a ti84 so you can reuse the answers to get it more exact. It is a rounded answer with rounds at each step.
First write the equation in slope-intercept form which is more commonly known as <em>y = mx + b</em> form where the <em>m </em>or the coefficient of the x term represents the slope of the <em>b</em> or the constant term represents the y-intercept.
Subtract 2x from both sides to get <em>y = -2x - 4</em>.
I put the x term first because that's how it is in y = mx + b form.
Now we can see that the <em>b</em> or the constant term is -4.
We can write this as the ordered pair (0, -4).
Keep in mind when writing a y-intercept as an ordered pair, your x-coordinate will always be 0 in the ordered pair.
The equation that models this relationship is y = 3x + 2.
