16. A 17. A 19) D 20) B.
16 For the following equations of the line:
a) y=3x-2 up 3
The equation /function describes a function 3x -2 up 3 units.
So since the 3x indicates the slope, of the line and we can infer that 3x -2 up 3 units is
y=3x -2 up 3 units
y= 3x -2 +3
y=3x +1
A
Now
17) What is the slope parallel to a y = 3/4 x -3
A parallel linear function has a slope with a slope in this case 3/4 x must be another function whose slope is equal.
Parallel lines, have the same slope so
A) 3/4
19) The slope of a Parallel line to -5x +y = 3
D Since it is parallel it has the same angle, so the slope is -5. Similarly to the previous one.
20.) Perpendicular lines have the negative inverse slope of an original line.
So for y= 4/3x -3
B
The slope for a perpendicular line is m = -3/4
