9. Given 8x+4y = 4, identify the slope and y-intercept.

A) Slope = -2 and y-int = 1

Step-by-step explanation:

The easiest way to get the slope and y-intercept from an equation is to put it in slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept.

So, let's subtract 8x from both sides, leaving 4y on the left side:

8x + 4y = 4 -> 4y = -8x + 4

Now, let's divide both sides by 4, so that we can have just y on the left side:

y = -2x + 1

-2 is the slope, and 1 is the y-intercept.

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
