Answer:
- your graph is correct
- y = 3x -5
Step-by-step explanation:
The graph shows you the line has a "rise" of 1-(-2) = 3 for a "run" of 2-1 = 1, so the slope is 3/1 = 3.
The y-intercept is seen to be -5, so the equation is ...
y = mx +b . . . . . where m is the slope (3) and b is the y-intercept (-5)
y = 3x -5
__
The points and line are plotted correctly, so you already have your graph.
Answer:
-2 , -2 , 0 , 1 , 2 , 4 , 7 , 8 , 9 , 12
Step-by-step explanation:
Order each number from least to greatest. Note that if the number is numerically larger and attached is a negative sign (-), then it is towards the least. If it does not have a negative sign, it leans towards the most.
Your answer:
-2 , -2 , 0 , 1 , 2 , 4 , 7 , 8 , 9 , 12

Answer:
13. A
14. C.
Step-by-step explanation:
A relation is a function if there is only one y assigned to each x.
That is if you have a set of points, there should be no repeated x value.
So looking at {(0,0),(-2,4),(-2,-4),(-3,7)} this is not a function because you have two x's that are the same. A.
The slope-intercept form of a linear equation is y=mx+b where m is the slope and b is the y-intercept.
The y-intercept is where the graph goes through the y-axis at. It goes through at -1 so b=-1.
The slope is rise/run. So starting from the y-intercept (0,-1) we need to find another point to count the rise & run to... How about (3,1)? That works. You can do the counting if you want. You could also use the slope formula.
To use the slope formula, I just like to line the points up vertically and subtract vertically then put 2nd difference over the 1st difference.
(0,-1)
-(3,1)
--------
-3 -2
So the slope is -2/-3 or just 2/3.
So the equation is y=2/3 x-1

Answer:
yes, yes, no, no
Step-by-step explanation:
An equation is linear if no term has a variable with an exponent other than 0 or 1. There can be no products of variables.
The equations with terms x³ or x² will not be linear.
(a, b) linear (yes)
(c, d) not linear (no)
