Answer:
Step-by-step explanation:
A fact family is a group of math facts using the same numbers. In the case of addition/subtraction, you use three numbers and get four facts. For example, you can form a fact family using the three numbers 10, 2, and 12: 10 + 2 = 12, 2 + 10 = 12, 12 − 10 = 2, and 12 − 2 = 10
I think that 10 students were reading during study time.
Well, first off let's check what is the slope of y = 2/3x+1.... .hmmmmm, notice
, since the equation is already in slope-intercept form, we can see it has a slope of 2/3.
well then, a line perpendicular to that one, will have a negative reciprocal to it.
so, we're really looking for the equation of a line whose slope is -3/2 and goes through 12, -6.
