Write the equation in y=mx+b form please????

Solnce55 [7]

ANSWER

$y = - 2x - 5$

EXPLANATION

We can use any two points to determine the slope.

The line passes through;

(-3,1) and (-5,5).

The slope is given by

$m = \frac{y_2-y_1}{x_2-x_1}$

This implies that;

$m = \frac{5 - 1}{ - 5 - - 3}$

$m = \frac{4}{ - 2} = - 2$

We can now find the equation using the formula;

$y-y_1=m(x-x_1)$

$y - 1 = - 2(x + 3)$

Expand:

$y = - 2x -6 + 1$

$y = - 2x - 5$

Answer:

Correct option is D $\frac{P}{(0.8)(1.08)}$

Step-by-step explanation:

Let the laptop's original cost be = L

After 20% discount its price will be (100 - 20)% × L = 0.8L

8% sales tax on this price = (100 + 8)% × 0.8L = 1.08 × 0.8L

So, p = 1.08 × 0.8L

⇒ L = $\frac{p}{(0.8)(1.08)}$
