If there are 20 rows each and 15 per row then you would multiply 20(15) = 300 then so there are 300 seats in Section J. each seat is 18$ so you would multiply 300(18) = 5400 so section J would get 5,400$ if it were to be sold out. The equation is 20(15)=300(18)=5400
In the first column you put 40 50 and 60
Then in the 2nd column you put those bombers into the equation (so you would write 3(40)+2 3(50)+2 and 3(60)+2) and then in the third column you solve them (so 3(40)+2=122 3(50)+2=152 3(60)+2=182)
And then you graph them at (40,122) (50,152) and (60,182)
to get the equation of any straight line, we simply need two points off of it, let's use the points from the picture below.
if we already have the slope, and we can see the y-intercept on the table, then we can simply use the slopel-intercept form and plug both of them in.
If we want to use slope-intercept form y=mx+b, pick two points and find the slope (value m on equation). Then find the coordinates of y-intercept (value b on equation).
