Answer:
y = - 0.5x
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 ) = (- 4, 2) and (x₂, y₂ ) = (2, - 1) ← 2 points on the line
m =
=
=
= - 0.5
The line crosses the y- axis at (0, 0 ) ⇒ c = 0
y = - 0.5x + 0 . that is
y = - 0.5x
Answer:
x < -6
Step-by-step explanation:
18 + x < 12
Subtract 18 from each side
18-18 + x < 12-18
x < -6
Answer: 2 kg
Step-by-step explanation:
3/4(22-x)=17-x
66/4-3/4x=34/2-x
33/2-3/4x=34/2-x
1/4x=1/2
x=2
Step-by-step explanation:
-4(4x-9)=2x
-16x+36= 2x
-16x - 2x = -36
-18x = -36
x = 2
