Answer: 0.4%

Step-by-step explanation:

Total number of people 9000, divide the number of allergic reactions 36 by 9000.

36/9000=0.004

Now multiply 0.004 x 100 to reveal percent allergic reaction

0.004 x 100 = 0.4%

0.4% had allergic reactions

Which equation represents a line that passes through (4, 1/3) and has a slope of 3/4
Ipatiy [6.2K]
Y = mx + b
m = slope of the line
b= y-intercept

Since you are given the point (4,1/3), the y-value is 1/3.
So plug in the numbers and solve for b:
(1/3)= (3/4)*(4) + b

After you solve the equation for b, you should get -2 2/3 or -8/3

No rewrite the equation with the y-intercept, b.

y = (3/4 x) - (8/3)
