The y-intercept is the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis.
The slope(m) is:
"rise" is the number of units you go up(+) or down(-) from each point
"run" is the number of units you go to the right from each point
You know:
y-intercept = -6 or (0, -6)
m = 2 or , so from each point you go up 2 units and to the right 1 unit to get to the next point.
#1: Locate the ordered pair (0, –6). From that point on the graph, move up 2, right 1 to locate the next ordered pair on the line. Draw a line through the two points.
This is true
#2: Locate the ordered pair (0, –6). From that point on the graph, move up 2, left 1 to locate the next ordered pair on the line. Draw a line through the two points.
This isn't accurate because the slope doesn't move left.
#3: Locate the ordered pair (–6, 0). From that point on the graph, move up 2, right 1 to locate the next ordered pair on the line. Draw a line through the two points.
This isn't accurate because (-6, 0) isn't the y-intercept or a point on the y-axis
#4: Locate the ordered pair (–6, 0). From that point on the graph, move up 2, left 1 to locate the next ordered pair on the line. Draw a line through the two points.
This isn't accurate because (-6, 0) isn't the y-intercept or a point on the y-axis, and the slope doesn't move to the left.
