Explanation:
M is the slope of the equation, basically how much the line goes up or down each unit. To calculate the slope, we divide the rise over the run or
[tex]\frac{y1-y2}{x1-x2}[/tex]
B is the y-intercept or when the line crosses the y-axis.
1. We can see the line moves 1 unit up every 3 units right. The line crosses the y-axis at (0,-4)
m = 1/3
b = -4
2. We can see the line goes 3 units down every 2 units right. The line crosses the y-axis at (0,4)
m = -3/2
b = 4
3. We can see the line goes 1 unit down every 4 units right. The line crosses the y-axis at (0,4)
m = -1/4
b = 4
4. We can see the line goes 1 unit down every 4 units right. The line crosses the y-axis at (0,2)
m = -1/4
b = 2
5. We can see the line goes 1 unit down every 1 unit right. The line crosses the y-axis at (0,1)
m = 1
b = 1
