What is y use the picture down below.
y=12x+3

y=12x−3

y=2x+3

y=2x−3

y = 2x - 3

Step-by-step explanation:

Slope-intercept form is y = mx + b

m = slope

b = y-intercept

If you look at the graph, the y-intercept is on (0, -3) which means the y-intercept is -3.

If you look at the slope, you can use the rise/run method. Let's use 2 as an example. We would turn it into a fraction, 2/1. You then want to use the rise/run method. Starting from the y-intercept, go up the amount of the first number, and then go right the amount of the second number. So we would go up 2 and 1 right.

So this is our answer, y = 2x - 3

no not all of them.

step-by-step explanation:

some of them have a square base.

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
