The graph you've provided shows a straight line on a coordinate plane. Let's break down the details of the line to better understand it:

Identifying Key Points

1. Slope (m):

   • The line slopes downward from left to right, indicating a negative slope.
   • Let's calculate the slope using two points from the graph:
     • Point 1: $(-9, 3)$
     • Point 2: $(6, -6)$
   • The slope formula is: $m = \frac{y_2 - y_1}{x_2 - x_1}$ Substituting the coordinates of the points: $m = \frac{-6 - 3}{6 - (-9)} = \frac{-9}{15} = -\frac{3}{5}$ So, the slope of the line is -3/5.

2. Y-Intercept (b):

   • The y-intercept is the point where the line crosses the y-axis.
   • From the graph, it crosses the y-axis at $y = 0.6$.

3. Equation of the Line: Using the slope-intercept form of a line $y = mx + b$, where $m = -\frac{3}{5}$ and $b = 0.6$, the equation of the line is: $y = -\frac{3}{5}x + 0.6$

Would you like more details or explanations on this? Here are five questions to explore further:

1. How do we interpret the slope of $-\frac{3}{5}$ geometrically?
2. How can we verify the y-intercept from the graph?
3. Can we rewrite the equation in point-slope form instead of slope-intercept form?
4. What happens to the line if we change the slope to a different value, like $-1$?
5. How do we find the x-intercept of this line?

Tip: To find the x-intercept of a line, set $y = 0$ in the equation and solve for $x$.
