when finding the intercept of a line with ax + by = c you make the other variable 0. This is due to the fact that if it is x intercept it it (x,0) and if it is y intercept it is (0,y) so if you plug in the other variable is 0.
x intercept : (5,0)
y intercept : (0,-2)
When finding a slop and knowing 2 points you can use the formula.
Yes he is correct because the 3 was in the tenths place. so say that the 3 is in the ones place multiply it by 10 and equales 3000. so you are just taking one zero with it
200 * 2/15 = the number of students that didn't read any books. This is 26.6, so 40 is not a good estimate 40 students is 20 percent versus 26 being approximately 13 percent.
