Answer:

y = -3/2x + 3

Step-by-step explanation:

We can get 2 points from the graph

(0,3)

(2,0)

from (0,3) we know that the b in the equation is 3

now to calculate m or slope we use $\frac{y1-y2}{x1-x2}$

$\frac{0 - 3}{2-0}$ = -3/2

so we plug our m and b into y = mx + b and get

y = -3/2x + 3

Put y-x=-8 of a line into slope-intercept form, simplifying all fractions.

grigory [225]

Answer: $y= x-8$

Step-by-step explanation:

Slope intercept form has a general formula of $y=mx +b$
m represents the slope of the line
b represents the value of the lines y-intercept

the equation must be rearranged into the general formula by isolating for 'y'

$y-x=-8$

to remove the x from the left side of the equation the opposite operation must be done to both sides

$y-x+x=-8+x$

the negative and positive x cancel out on the left side, leaving us with the equation with y by itself
now you can rearrange to put the equation into $y=mx+b$

Final Answer: $y=x-8$

Sphinxa [80]

Answer:-

x=-5/2

Step-by-step explanation:

x+2/3=-1/6

after cross-mutiplying,

6(x+2)=-3

6x+12=-3

** Calculation is based on 52 weeks per year.

$\smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile \smile$

$\boxed {Annual \ Premium \ = \$2530}$

Your employer is paying 75% of the Premium:
$\boxed {75\% \ of \ \$2530 \ = \ 0.75 \times 2530\ = \ \$1897.50}$

Amount you need to pay:
$\boxed { \$2530 - \$1897.50 = \$632.50}$

Amount needed to be deducted weekly from paycheck:
$\boxed{ \$632.50 \div \ 52 = \$12.16}$

$\Bigg( \boxed{ \boxed {Ans: \$12.16 }} \Bigg)$
