The answer for 7 x 42 is 294.
Well, since the graph starts at (0,50), making our y-intercept 50, we can knock off D as an option.
The next step is to find the slope. To do this, find two points and subtract the y values over the x values. (Just make sure that whichever y value you start with - start with the same x value).
So we have >>> (50, 200) and (0,50) from earlier.
200 - 50 / 50 - 0 = 150/50 or 3/1, or 3.
This makes the correct answer A since the equation is represented as y = mx + b, where m is the slope and m has a value of 3.

Answer:
n = 6
Step-by-step explanation:
the formula for interior angle is ( n-2)
but we given the measure of one angle, so solve
720 = (n - 2)180
720/180 = (n - 2)
4 = (n - 2)
combine the like terms
4 + 2 =n
6 = n
