OKAY, so I'm going to start with Q2 (not 100% sure how to work out 1, but lets use process of elimination). Firstly, the rule is y=mx+c So, start with the first line y=2x-3, from this the first thing you need to do is find the y-intercept (m) and the gradient (c). So, this is very simple 2 is m and -3 is c (if you look at the rule it matches up). m=2/1(this is rise/run, rise is how much you go up by, and run is how much you go left or right by (left if positive, right if negative)) c=-3 Now, go to your graph, and look on the y line and go to -3. Then go left, 1, and up 2. IS THERE A LINE CROSSING THROUGH THIS POINT? Yes? Good. Now for y=-1/2+1. Looking at the rule again (y=mx+c), m=-1/2 (rise/run) c=1 NOW, once again go to your graph, and look on the y line and go to 1 (in this case the line actually passes through this point), now go right 2 places and up 1. IS THERE A LINE? Yes? Good!
NOOOW, for Q3, use the same steps and you will have the answer. y=1/4x-2 m=1/4 (rise/run) c=-2 Look at graph C, start at -2 on the y line, go left 4, and up 1? Yes? Line crossing through this point? good!! Now for the 2nd one, y= -2/5x+4 m=-2/3 c=4 Look at the same graph start at 4 on the y line, go right 5 and up 2! Got it? There's a line crossing through this point, yes? YAY
Now I have no idea how to do Q1, but by process of elimination it's pretty obvious. I hope this is right! Okay, bye!! :D
The appropriate response is letter B. The connection is no doubt a causation is the positive relationship between's the quantity of trucks that drive on a street and the measure of support the street needs
A. People who are related to the employees of Isaac's Immaculate Ice Cream
Step-by-step explanation:
If the results are called into question, this means there is potential bias in the survey.
Randomly choosing people from a phone book or another random method would not create bias.
Having people blindly test brands of ice cream would not create bias, as it is random and fair.
However, if the people surveyed were related to employees of Isaac's Immaculate Ice Cream, the results could be called into question over a fear of favoritism.
