Answer:
y = 3x - 7
Step-by-step explanation:
Slope-intercept form:
y = mx + b
Where:
y is the y value.
m is the slope.
x is the x value.
And b is the y-intercept.
First, you want to find your slope. To do this, you can either use the slope formula to find the slope, or just count on the picture:
m = rise/run
m = 3/1
m = 3
With the slope formula, you first need to choose two points.
I chose:
(2, -1) and (3, 2)
Slope formula:
m = (y2 - y1) / (x2 - x1) {It doesn't matter which point you choose to be x2 and x1, just be consistent when you plug it into the formula}
m = (2 - (-1)) / (3 - 2)
m = 3/1
m = 3
Now that you have your slope, all you need is your y-intercept. To find your y-intercept, you can either look at the graph (again) to see where the line intersects with the y-axis, or you can solve it algebraically:
y-int = -7
To solve algebraically, choose a random point on the line and plug it into what you have for your equation so far and then solve for b.
I chose:
(2, -1)
y = 3x + b
-1 = 3(2) + b
-1 = 6 + b
-1 - 6 = b
b = -7
Now you have your final answer:
y = 3x - 7
Answer:
P = 2n + 8m - 1
Step-by-step explanation:
A <u>trinomial is an expression or equation that has three terms</u>. A term is when between the numbers or variables, the operations are neither subtraction nor addition, or when there is only one number.
If two terms have the <u>same variable</u>, called <u>like terms</u>, they can be combined by addition or subtraction.
The perimeter is the total length of all the sides.
The formula for the perimeter of a triangle is 
for each of the three sides.
Substitute each of the three sides.
brackets can be removed
rearrange equation according to like terms
collected the like terms by addition
Answer:
y = -1/2 | x+3|
Step-by-step explanation:
y = f(x + C) C > 0 moves it left
C < 0 moves it right
y = Cf(x) C > 1 stretches it in the y-direction
0 < C < 1 compresses it
y = −f(x) Reflects it about x-axis
Our parent function is
f(x) = |x|
We want it 3 units left
y = f(x + 3)
y = |x+3|
Then reflected across the x axis
y = −f(x)
y = -|x+3|
Then shrink by 1/2 vertically
y = Cf(x)
y = -1/2 | x+3|
