What’s the equation in slope-intercept form?

Varvara68 [4.7K]

You can take any 2 points from the table and calculate the slope, as follows:
-2-(-4) 2
m = slope = ---------- = ------ = -1/5
-5 - 5 -10
The slope-intercept form is y = mx + b. You already know m (which is -1/5), and have several points from which to choose to obtain x and y. Let's use the given point (-2, -1).

Then -1 = (-1/5)(-2) + b, or -1 = 2/5 + b. Solve for b.

-5 = 2 + 5b, so 5b = -7, and b = -7/5.

The desired equation is y = (-1/5)x - 7/5.

(5a-2)(5a+2)-3(1-a)-3a=

attashe74 [19]

So first we need to know the order of operations
P - Parenthesis
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction

Then the special cases:
(I have attached a picture below)

Lets get into action!
(5a - 2)(5a + 2) - 3( 1 - a ) - 3a
25a² - 4 - 3 + 3a - 3a
25a² - 7
25a² - 7 is the answer

Which of the following data sets represents a linear function?

Leokris [45]

Answer:

Step-by-step explanation:

to be a linear function the change in X and the change in Y has to be the same hence slope

A. x changes by+ 1 see 2,3,4,5, and y changes by +5, +7, +9 so A is not a linear function

B. X changes by -1 in all, y changes +1 for first 3 then -1 last, so B is not a linear function

C. X changes by +1 for all and y changes by -6 for all so is it is a linear function

D x changes by +1 for all and y changes by -1, +1, +3 so no linear fn.
