Question

PLEASE EXPLAIN THIS TO MEEEE (image included)

PLEASE GIVE ME AN EXPLANATION THAT I CAN REALLY UNDERSTAND

Answer 1

A

Explanation:

Substitute in the equation remove each x and put 1 if the result is 4 that's mean it's the true equation

Answer 2

first option

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 =
`(y_(2)-y_(1) )/(x_(2)-x_(1) )`

with (x₁, y₁ ) = (1, 4 ) and (x₂, y₂ ) = (3, - 4 )

m =
`(-4-4)/(3-1)` =
`(-8)/(2)` = - 4 , then

y = - 4x + c ← is the partial equation

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

using (1, 4 ) , then

4 = - 4 + c ⇒ c = 4 + 4 = 8

y = - 4x + 8 ← equation of line
