Solve this. i don't understand. also, explain. i'll give brainliest if you're right.

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 = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 3, 3) and (x₂, y₂ ) = (0, 4)

m = =

Note the line crosses the y- axis at (0, 4) ⇒ c = 4

y = x + 4 ← equation of line

-y = 1/3 x + 4 is the correct answer on E2020

Step by-step explanation:

I just took the test and this was right.

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.
