Answer:
The second one.
Step-by-step explanation:
The slope of the graph, -1/3, is going down from left to right because it is negative, so it is decreasing. Slope is the rise over run, so because the slope is -1/3 look for lines that go down 1 unit and across 3 at the same time (from one corner of a square to the other). Then, because your y-intercept is a 5, just look for your line to cross the y-axis at 5. And that's it.
The number that substitutes y is 20. To solve this you need to set up a proportion, or what looks like this:
8/10=16/y
Then, look at the 8 (the numerator) and find how many times it goes into 16 (the other numerator). 8*2=16, so the pattern is to multiply 810*2/2. Your answer should be:
8/10*2/2= 16/20!!!
I really hope this helped you!
Answer:
Step-by-step explanation:
The lines in the graph part C don’t intersect at two whole numbers on the coordinate grid. Estimate the values d the solution to the nearest one-fourth of a unit. Then substitute the x- and y-values of the approximate solution into the two equations. How close do you get to the constant numbers in each equation?
