Slope = 5/8
--------------------------
Equation:
--------------------------
y = 5/8 x + b
--------------------------
Find y-intercept :
--------------------------
At (8, 2),
2 = 5/8 (8) + b
2 = 5 + b
b = 2 - 5
b = -3
--------------------------
Equation :
--------------------------
y = 5/8x - 3
-----------------------------------------------------------------
Answer: y = 5/8 x - 3

Answer:
<em>Hello.</em>
An expression does not have an equal sign in it. Here are three examples:
2x + 7y + 6
x + 3y - 6
4x/4y x 6 Good luck!
To find the answer:
The probability of getting a ten:
=4/52
The probability of getting a king:
=4/52
The probability of getting a diamond:
=52×1/4
=13/52
However,there would be king and ten of diamond which overlapped and therefore -2/52 would be in the equation.
We can then sum up to find the equation:
=4/52+4/52+13/52-2/52
=21/52-2/52
=19/52
Therefore the answer is 19/52.
Hope it helps!
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
