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.

b

step-by-step explanation:

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
