What is the equation in slope-intercept form of the line that passes through the points (0, −4) and (2, 0)?

Nastasia [14]

Answer:

$y = 2x -4$

Step-by-step explanation:

Slope intercept form is $y = mx + b$ where m is the slope and b is the y-intercept.

Slope is $\frac{rise}{run}$ or $\frac{y_2 - y_1}{x_2-x_1}$ in this case = $\frac{0 - (-4)}{2 - 0} = \frac{4}{2} = 2$

Substitute one of the coordinates for x and y. I am going to use (0, -4) so:

$-4 = 2(0) + b\\-4 = 0 + b\\-4 = b$

since m = 2 and b = -4, we can conclude that the equation would be

$y = 2x -4$

$40 \times 0.80 = 32$

$32 \times 12 = 384$

He gains £384

$40 - 32 = 8$

$8 \div 2 = 4$

$2(12) + 2(6) = 36$

He gains £36

$- 130 + 384 + 36 = 290$

Ryan made £290

I'm not too sure about this...

Anyway if he sold 80% of the jumpers at a normal price, he would earn £384.

There are 8 left and he managed to sell half of those but there is a promo where you can buy one at full price and get one for half the price so only two of the four can be bought at full price while the other two gets bought at half price. He earns £36 from this.

If you take in account the starting cost and add the profits, he made a total of £290 selling jumpers.

But again, I'm not too sure.
