Answer:
y-intercept: (0,6)
slope = -2
equation: y = -2x + 6
Step-by-step explanation:
1) First, identify the y-intercept. The y-intercept is the point at which the line intersects the y-axis. We can see that the line crosses the y-axis at (0,6), so that must be it.
2) Now, find the slope. Pick two points from the line. I chose (0,6) and (3,0). Then, substitute the two points' x and y values into the slope formula 
and solve:
So, the slope is -2.
3) With the found information, use the slope-intercept formula 
to write the line's equation. Substitute values for the 
and 
.
represents the slope, so substitute -2 in its place. represents the y-intercept, so substitute 6 in its place. This gives the following equation:

Answer:
Half of the diameter is equal to the radius.
Ok so to find the sum of interior angles the formula is
s=180(n-2)
s is sum and n is the number of sides
so this is a quadrilateral cause it has 4 sides
because of that n=4
substitute
s=180(4-2)
now you can either distribute or do pemdas but its easier and more efficient to just do pemdas
s=180(2)
s=360 degrees
