The slope-intercept form of the linear function is y = m x + b , where m is the slope and b is y-intercept.
Here we have: y = 3 x - 3
a ) When y = 0
0 = 3 x - 3
- 3 x = - 3
x = ( - 3 ) : ( - 3 )
x = 1
When x = 0
y = 3 * 0 - 3
y = - 3
So x - intercept is ( 1, 0 ) and y-intercept is ( 0, - 3 ).
b ) The slope:
m = ( y2 - y1) / ( x2 - x1 ) =
= ( - 3 - 3 ) / ( 5- 7 ) = ( - 6 ) /( - 2 ) = 6 / 2 = 3
Answer: The slope m = 3 .
60 is the base OK. I think am right
7 x 21 is equivalent to 21 x 7
also 3 x 49
A. Class A
A higher mean equals higher median overall.
B. Class B
The range of a data is the difference between the greatest value and the smallest value; a lower range would infer that the data's range is not very wide, and thus is not very varied.
Answer:D
Step-by-step explanation:
so the bins are 18-24, 25-31, 32-38, and 39-45.
the order is 20, 40, 120, and 80.
So if you match them up you get:
18-24 20
25-31 40
32-38 120
39-45 80
The only answer with all of those is D
