To find the equations of the lines based on the provided points:
Solid Line
-
We have points (0,0) and (1,5) on the solid line.
-
The slope (m) can be calculated using the formula \( m = \frac{y_2 - y_1}{x_2 - x_1} \):
- Let (x1, y1) = (0, 0) and (x2, y2) = (1, 5).
- Slope \( m = \frac{5 - 0}{1 - 0} = \frac{5}{1} = 5 \).
-
The equation of the line in slope-intercept form is \( y = mx + b \).
- Since the line passes through the origin (0,0), we know \( b = 0 \).
- Therefore, the equation is:
\[ y = 5x \]
Dotted Line
-
The points (0,3) and (1,5) lie on the dotted line.
-
Calculate the slope:
- Let (x1, y1) = (0, 3) and (x2, y2) = (1, 5).
- Slope \( m = \frac{5 - 3}{1 - 0} = \frac{2}{1} = 2 \).
-
Using the slope-intercept form, and since the line passes through (0,3), we have \( b = 3 \).
- So, the equation of the dotted line is:
\[ y = 2x + 3 \]
Summary
The system of equations based on the graph is:
- The equation of the solid line is \( y = 5x \).
- The equation of the dotted line is \( y = 2x + 3 \).
