1. Identify whether the slope is positive, negative, zero or undefined. Please show work or explain answer so that I can understand it
Please see attachment for graph for question 1.
2. Find the x- and y-intercepts for the equation. Then graph the equation. Please show work.
-3x - 6y = 18
Please see attachment for answer choices for question 2.
3. Decide whether the pair of lines is parallel, perpendicular, or neither. The line through (-20,5) and (-4,7) and the line through (-5,5) and (7,4). Please show work and explanation.
4. Write an equation in standard form for the line passing through the pair of points (7,8) and (7,-8). Please show work.
a) -8x + 8y = 0
b) y = 8
c) x = 7
d) 8x - 8y = 0
The answer is D.
When the line is vertical, the slope is undefined.
