Answer:
A. There is a positive correlation in the data set
Step-by-step explanation:
First, we need to determine if there is a correlation or not, this means that the points in the scatter plot follow a specific pattern or not. This scatter plot does appear to follow a linear pattern, therefore the answer must be A or B. Next, we evaluate if there is a positive or negative correlation based on if the pattern of the points is increasing or decreasing, based on the graph, it appears to be increasing so we can determine that there is a positive correlation. Based on these, we can determine that A is the correct answer.
Answer:
D) y=2/9x2+2x+4
Step-by-step explanation:
y-intercept=4
2 x intercepts= 3 and 6
so y-intercept is point where x is 0 like (0,y)
x-intercept is the opposite y is 0 (x,0)
that means y-intercept is (0,4)
x-intercept is (3,0) and (6,0)
the formula of slope intercept form is
y=mx+b
b= is y-intercept
that means
y=ox^2+mx+4
x-intercept is point where y is 0
so solve
now lets try the first option
This is are quadratic functions
you need to plug in both of these until u get one that is right
change the y until you get both x's
the first option if wrong
second one y = 6x2 + 3x +4 has no x-intercepts
3rd option y=3/4x^2-6x-4
last option is y=
2/
9
x2+2 has points at -6. and -2.9999 or -3

Answer: y = 9x - 11
Step-by-step explanation:
The equation of a straight line can be represented in the slope-intercept form, y = mx + c
Where c = y intercept
m represents the slope of the line.
m = (y2 - y1)/(x2 - x1)
y2 = final value of y
y 1 = initial value of y
x2 = final value of x
x1 = initial value of x
The line passes through (4, 25) and (8, 61),
y2 = 61
y1 = 25
x2 = 8
x1 = 4
Slope,m = (61 - 25)/(8 - 4) = 36/4 = 9
To determine the y intercept, we would substitute x = 4, y = 25 and m= 9 into y = mx + c. It becomes
25 = 9 × 4 + c
25 = 36 + c
c = 25 - 36
c = - 11
The equation becomes
y = 9x - 11
No its not, the equation your showing right now adds up to 68
