(0, 3)
<span>-x + 3y=9
to figure out the y-intercept, you must put the equation into y-intercept form first: y = mx + b
</span><span>-x+3y=9
3y = x + 9
y = (x/3) + (9/3)
y = x/3 + 3

Answer:
22.5 miles
Step-by-step explanation:
If 2 inches equal 15 miles then 1 mile equals 7.5 miles. 15/2=7.5
7.5 x 3=22.5 miles.
Answer:
Rotation:
Step-by-step explanation:
Translation is usually movements like up, down, left, right.
Dilation is when one shape is bigger/smaller than the other, but still congruent.
Reflections are usually done over an axis (x or y), and don't change the degree at which a shape is turned. From looking at the triangles, you can see that one triangle was turned clockwise.
Answer:
No solution
Step-by-step explanation:
This is just a simple system of equations.
y=-1/4x+2
8y+2x=-40
Get the same variables onto their corresponding sides, so it will look like this:
y=-1/4x+2
8y=-2x-40
Now here, you have to be careful, because to solve for the system of equations, you need to make sure you are multiplying the equation proportionately.
8y=-2x+16
8y=-2x+40.
But here you see that they share the same variables in a similar format, but their values are supposed to be different, meaning that this equation is a false claim. So you would respond to the question as "no solution.
