A line passes through the point (0, –1) and has a slope of -2/3 What is the equation of the line?

1 answer:

6 0

The slope formula:
$y=mx+b$
m - a slopeb - y-intercept
We have:
$m=-\dfrac{2}{3}$ and point $(0;-1)\to b=-1$
Substitute:
$y=-\dfrac{2}{3}x-1$
Answer: A.

Multiply 1.5 by 3 which equals 4.5

Multiply 1.5 by 2 which equals 3

Add the above answers (4.5 plus 3)

Then multiply by 2 (7.5 times 2)

It equals 15

I hope this helps and that this is the right problem. There is no picture shown but I just did this problem for someone else so I thought I would take a shot at it :)

Use the given graph to determine the limit, if it exists.

Ahat [919]

The limit in the given graph $\lim_{x \to \ 2^{-} } f(x)$ is 3 and $\lim_{x \to \ 2^{+} } f(x)$ is -2

Given graph of a function and we have to determine the limits when x tends to 2 minus and when x tends to 2 plus.

When we see the graph we can find that the graph is not of the linear function because it is not straight line.

From x=2 and onwards it gives values values of only -2 because it is parallel to x-axis at y=-2.From x=2 and leftwards it gives values values of only 3 because it is parallel to x-axis at y=3.

Hence the limit of the function whose graph is shown is 3 and -2.

Simplity 2(- 4)+7(x + 2).

Evgesh-ka [11]

Answer:

Step-by-step explanation:

To find your answer you first have to multiply the numbers that aren’t in parentheses and you multiply 2 and 7 and you get 14 then you don’t have to worry about the x because it is a variable so now add -4 +2. but first we have to turn negative into positive so you add -4 + 8
