Answer:
k = - 2j + 28
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 ) = (14, 0 ) and (x₂, y₂ ) = (0, 28 ) ← 2 points on the line
m = =
= - 2
The line crosses the y- axis at (0, 28 ) ⇒ c = 28
In this graph the y- axis is the k- axis and the x- axis the j- axis , then
k = - 2j + 28 ← equation of line

Answer:
Option A. and
Step-by-step explanation:
we know that
The solution of the first inequality is the shaded area below the solid line
The solid line passes through the points (0,4) and (3,0) (the y and x intercepts)
therefore
The first inequality is
The solution of the second inequality is the shaded area to the right of the solid line x=0
therefore
The second inequality is
