Answer:
i am not sure i think its either c or b
Step-by-step explanation:
Answer:
y=2x-3
Explanation:
which equation represents the relationship between x and y shown in the table?
x | y
2 | 1
4 | 5
6 | 9
8 | 13
take a look at the values in the table one more,
we find the gradient of the line to be
G=y2-y1/(x2-x1)
G=13-1/(8-2)
slope/gradient=12/6
m=2
from equation of a line graph, we know
y=mx+c
m=gradient
c=intercept
y=vertical axis
x=a point on the horizontal axis
y=2x+c
when x=6, y=9
9=2(6)+C
c=-3
Therefore the equation becomes
y=2x-3
Step-by-step explanation:
Answer:
y = -1x + 3 or y = -x + 3 (**That is the last option which is D**)
Step-by-step explanation:
You need to do slope-intercept formula and the slope formula.
The Slope-Intercept Formula: y=mx+b
The Slope Formula: y2 - y1 / x2-x1
Your coordinates:
(-1,4) and (1,2)
2 - 4/1- (-1)
-2/2
Simplified is -1
Your "m" in the slope-intercept formula is -1
Formula: y=-1x + b
Now, you need to find the Y-Intercept which is the "b"
Using our slope-intercept formula, you need to plug in "x1" and "y1"
4 = -1(-1) + b
4 = 1 +b
4-1 = b
3 = b
So your equation is:
y = -1x + 3 or y = -x + 3
Answer:

Step-by-step explanation:
Let w=width
And let l=length
Perimeter is the distance all the way around the outside of the shape. Add up all the sides to find it.
