Answer:
3
Step-by-step explanation:
so.i think y=3x+b. I'm not completely sure but y2-y1 over x2-x1
The median of the numbers would be 7.5
We know that the sum of the interior angles of a triangle equals 180, then,in this case we have the following equation:

then, solving for b, we get:

now that we have that b = 41, we can find the measure of each angle:
i dunooo i dont even nooooo
The y-intercept is (0, 2), because it's the spot where the line crosses the y-axis. The other point showed on the graph is the x-intercept..
