30 points Given (-3, 1) and (3,-3). The slope of the line is ____________ . The equation of the line is _____________.
Liono4ka [1.6K]

Answer:

y = (3/2)x + 11/2

Step-by-step explanation:

As we move from the point (-3, 1) to the point (3, -3), x increases by 6 and y decreases by 4.  Thus, the slope is

m = rise / run = 6/4 = 3/2.

Subbing the knowns into the general point-slope form of the equation of a straight line, we get

y - 1 = (3/2)(x - [-3]), or y - 1 = (3/2)(x + 3).

This is equivalent to y = (3/2)x + 9/2 + 1, or y = (3/2)x + 11/2.

How many solutions does the equation -4y + 4y + 2=2
Luden [163]

Answer:

Infinite Solutions

Step-by-step explanation:

If you look at the equation careful you will see this part "-4y+4y".  If you see that the variables cancel each other out leaving 2=2.  That means that for any value of y, 2=2.  Because the variable cancels itself out it doesn't mater what the variable is.  So there is an infinite amount of values you can have for "y".

Write the ratio as a fraction in simplest form.<br><br> $5.40 for 24 cans (per can)
galina1969 [7]

Answer:

9/40

Step-by-step explanation:

To find the price per can, we take the cost and divide by the number of cans

$5.40/24

5.4/24

Since there is a decimal in the numerator, multiply the top and bottom by 10

5.4/24 * 10/10

54/240

Divide the top and bottom by 6

9/40
