Answer:
y = 3x - 7
Step-by-step explanation:
The <em>point-slope formula</em> for a straight line is
y – y₁ = m(x – x₁)
x₁ = 4; y₁ = 5; m = 3 Substitute the values
y – 5 = 3(x - 4) Remove parentheses
y – 5 = 3x - 12 Add 5 to each side
y = 3x - 7
The graph is a straight line with a y-intercept at y = -7 and a slope = 12/4 = 3.
We need slope/rate of the table
Slopes of all options
- 5/7=25/21
- 3/5=9/15
- 1/3
- 7/9
- 7/11=21/33
Option D is correct
Option
6x - 4y = 8...solve for x
6x = 4y + 8
x = (4/6)y + 8/6
x = 2/3y + 4/3 <==
Answer:
Linear Equation
Step-by-step explanation:
I cant really see the graph but i think that its linear equations because
A linear equation is an equation that may be put in the form where are the variables, and are the coefficients, which are often real numbers.
So, therefore, i beleive its an linear equation
Answer:
<h2>C) r = − 1</h2>
Step-by-step explanation:
In the graph, you can observe that all five points are perfectly lined up on a straight line, which is decreasing, because each points is lower than the previous one.
This situation represents a coefficient of correlation of -1, which means there's a strong negative correlation between variable.
Once again, graphically, this strong negative correlation can be deduct from the behaviour of the data, which is clearly decreasing with a straight line behaviour. In other words, the line that best fits is almost unique.
Therefore, the right answer is C.
