They are stupid. correlation is always between -1 and +1
<span>These types of lines are called contour lines. Though the image is flat and on a two dimensional sheet of paper, they suggest the volume of the shape. Such drawings are often done very quickly or with a single hand motion.</span>
Answer:
y = - 3x + 19
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 )
Here m = - 3, thus
y = - 3x + c ← is the partial equation
To find c substitute (6, 1) into the partial equation
1 = - 18 + c ⇒ c = 1 + 18 = 19
y = - 3x + 19 ← equation of line
9 < x
this means that x is a larger number than 9
9 = x
this means that x is equal to 9
