What is an equation of the line that passes through the points (-6, -4) and (3, 8)

y = x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m =

with (x₁, y₁ ) = (- 6, - 4) and (x₂, y₂ ) = (3, 8)

m = = = = , then

y = x + c ← is the partial equation

To find substitute either of the 2 points into the partial equation

Using (3, 8 ) , then

8 = 4 + c ⇒ c = 8 - 4 = 4

y = x + 4 ← equation of line

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
