The one missing is the fourth choice.
As you can see, the x axis stands for the weight, and the y axis the total cost.
You can see that the point, (1, 4) definitely exists.
So basically it would be 1 pound of cheese for four dollars, since x is weight and y is total cost.
You can see the fourth choice states that it's four dollars for one pound of cheese.
Hope this helped :)
The answer to your question is a=124 because the center triangle is a isosceles triangle
Given two points (x₁,y₁) and (x₂,y₂) the slope of the line that passes through theses points will be:m=(y₂-y₁)/(x₂-x₁)
We have two points A(-2,-2) and B(2,-2); therefore the slope will be:m=(-2+2)/(2+2)=0/4=0
slope-intercept form:y=mx +bm=slopeb=y-intercept =-2
y=0x-2y=-2
Answer: The slope of diagonal AB is 0 and its equation is y=-2
N=8 is the correct answer
