Answer:
B. y - 1 = -4[x - (-3)]
Step-by-step explanation:
Given:
Slope = -4
Point = (-3, 1)
Required:
Point-slope form of the line
Solution:
Equation of a line in Point-slope form is given as y - b = m(x - a).
Where,
a = -3
b = 1
m = -4
Plug in the values
y - 1 = -4[x - (-3)]
Answer:
The equation would be 2,250 - 120<em>m</em>
Answer:
A. negative correlation
Step-by-step explanation:
Let two variables x and y, the correlation coefficient r measure to what degree the variables x and y are related.
--- If this coefficient is positive then the relationship will be positive. This means that even an increase in the variable x will produce an increase in the variable y. In the dispersion diagram the points will be grouped, simulating a line of positive slope.
--- If this coefficient is negative then the relation will be negative. This means that even an increase in the variable x will produce a decrease in the variable y. In the dispersion diagram the points will be grouped, simulating a negative slope line.
In the diagram shown it can be noted that as the variable x increases the variable y decreases.
Therefore it can be concluded that the correlation between x and y is negative. The correct option is option A
Y=mx+b is what I learned and point slope is y-y1=m*x-x1
