Answer:

y = 2x - 3

Step-by-step explanation:

To solve for y, use the point slope formula: y2 - y1 / x2 - x1

Given the points (3, 3) and (4, 5) 5 - 3/4 - 3

2/1

m = 2

Use the slope m = 2 and one of the given points such as

(3,3) to substitute for x1 and y1 in the point-slope form

So, y - y1 = m x (x - x1)

y - (3) = 2 x (x-3)

Solve for to get the equation. y = 2x - 3

Mallory works 20 hours a week as a website designer and earns $42.50 per hour. If Mallory saves

AleksandrR [38]

If Mallory makes $42.50 per hour and she works 20 hours a week, we multiple those two and we get:

42.5 * 20 = 850

So she earns $850 per week.

Mallory saves half of that amount she would have $425 per week.

In 4 weeks she would have:

425 * 4 = 1700

Mallory will save $1,700 in four weeks.

What multiplication expression can be broken apart into (3x4) + (3x4) using the distributive property

Anna007 [38]

The original expression here might be (4x3) + (4x3). This is because the distributive property simply moves around numbers, but will not change the value of the equation, as in the question we are looking at here.
