Which statements accurately describe how to determine the y-intercept and the slope from the graph below?
On a coordinate plane, a line goes through points (0, negative 6) and (3, 0).
To find the y-intercept, begin at the origin and move horizontally to the graphed line. To find the slope, use two ordered pairs on the line and substitute into the equation m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction.
To find the y-intercept, begin at the origin and move horizontally to the graphed line. To find the slope, use two ordered pairs on the line and substitute into the equation m = StartFraction x 2 minus x 1 Over y 2 minus y 1 EndFraction.
To find the y-intercept, begin at the origin and move vertically to the graphed line. To find the slope, use two ordered pairs on the line and substitute into the equation m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction.

Answer:
summary
Step-by-step explanation:
Answer: Choice C
To find the y-intercept, begin at the origin and move vertically to the graphed line. To find the slope, use two ordered pairs on the line and substitute into the equation m = (y2-y1)/(x2-x1)
============================================
Explanation:
The y intercept is where the graph crosses the vertical y axis. So that's why we move vertically from the origin to get to the graph.
The slope is calculated as the difference of y values over the difference in x values. We subtract in the same order for both. In other words,
slope = rise/run = (change in y)/(change in x)
Positive slope means the line goes uphill when you move from left to right. Negative slope means the line goes downhill when you move from left to right.
A line N passes through the points (–1, 4) and (–1, –4).
Which is true of line N?
1. Line N is a vertical line with an undefined slope.
2. Line N is a vertical line with a slope of zero.
3. Line N is a horizontal line with an undefined slope.
4. Line N is a horizontal line with a slope of zero.
(Please help, I'm timed)
Answer:
1 and 2
Step-by-step explanation:
When you look at both of those points on a graph the line is linear and vertical; undefined

Just 2 slope questions of math!!! please help <3 i would genuinely appreciate it
Answer:
B: -5/4
Step-by-step explanation:
Starting from the point on the left at (-3,-2), you go to the left 4 which is the positive direction, and down 5 which is the negative direction. This brings you to the other point at (1,-3).
Hope this helps! :)
