Im not sure, maybe determined answer B
X < 31.5
answer is the middle symbol
start at 31.5 (right in the middle between 31 and 32) move open arrow to the left
y-intercept -3
slope 1/2
is sufficient info with which to write an equation for a straight line:
y = mx + b becomes y = (1/2)x - 3.
You should check this by determining whether or not (2,-1) satisfies this equation.
Using the probability concept, it is found that there is a
