Which point-slope form passes through the point (-2,1) and has a slope of 3?

Mathematics

The formula for point slope form is (y-y1) = m(x - x1)

In this formula m will always be the slope. So, you can substitute 3 in for m

(y-y1) = 3(x-x1)

y1 is the y-coordinate and x1 is the x-coordinate. So, you can substitute them in and you will be done.

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

But since it is minus a negative it changes to a positive so it would be:

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

Hope this helps!

Find two postive numbers such that the ratio of the two numbers is 5 to 3 and the product of the two numbers is 540.
svet-max [94.6K]

Answer:

337.5 and also 202.5

Step-by-step explanation:

do 8x = 540 since 5 and 3 are in a ratio... so you get 5x plus 3x. Then you solve for x and get 67.5..67.5 times 3 is 202.5 and 67.5 times 5 is 337.5.
