Answer:
14. y = x - 6
15. [tex]y = -\frac{1}{2}x-5[/tex]
Step-by-step explanation:
Slope-intercept form is y = mx + b where:
"m" is the slope
"b" is the y-intercept
"x" and "y" are points on the graph.
For each question,
- Find the slope by counting rise over run between two points
- Find the y-intercept by where the graph hits the y-axis
- Substitute the slope and y-intercept into y = mx + b
14.
Slope:
Two points are (6, 0) and (7, 1).
[tex]m= \frac{rise}{run} \\=\frac{1}{1}\\= 1[/tex]
Y-intercept:
b = -6
y = 1x - 6
We don't need to write the 1.
∴ The equation is y = x - 6
15.
Slope:
Two points are (-2, -4) and (0, -5).
[tex]m = \frac{rise}{run}\\=\frac{-1}{2}[/tex]
Y-intercept:
b = -5
∴ The equation is [tex]y = -\frac{1}{2}x - 5[/tex]
