Statistic significance requires that your sample be representative of the population, but I'm struggling with this because if the class is an elective then the answer would be: <span>No, it is not a valid inference because she asked all 22 students in her science class instead of taking a sample of the students in her school.
BUT if the class is required, as most science classes are, then it WOULD be a random sample of the school. So the last option would be correct.
My guess though is that the teacher is looking for answer B.

Hey there! :)
Please keep in mind that slope-intercept form is : y=mx+b ; where m=slope, b=y-intercept
Using this, we can isolate y in our original given equation.
12x - y = 4
Start off by subtracting 12x from both sides.
-y = -12x + 4
Divide both sides by -1.
-y ÷ -1 = (-12x + 4) ÷ -1
Simplify!
y = 12x - 4
Therefore, using the slope-intercept form, we can come to the conclusion that because 12 is located in the "m" slot and "m=slope" then 12 is our slope. In addition, -4 is our y-intercept because it is located on the y position.
Slope = 12
Y-intercept = -4
