I can see from the image that there are multiple math problems written on the board, involving coordinate geometry, linear equations, and gradient (slope). Here’s an overview of the topics based on the numbers:

1. (−9, 5), m = 3: Find the equation of a line with slope $m = 3$ that passes through the point $(-9, 5)$.
2. (−9, 2) and (6, −1): Find the equation of the line passing through these two points.
3. (4, −2) and (−8, −9): Same type of problem, finding the equation of a line through these points.
4. (3, 1): Appears to be labeled "segaris," which in Indonesian means "collinear." This could relate to checking if points are collinear.
5. (3, −3): Labeled similarly as above. Could be checking collinearity for another point.
6. "gambar grafik": Likely asking to sketch the graph of $y = x^2 + 14x + 49$, which is a quadratic function.
7. "mencari gradien": This translates to "find the gradient" for the equation $9x − 6y = 10$.
8. "mencari gradien": Find the gradient for the equation $2x + 3y = 12$.
9. (5, 2) and (7, 9): This could be another line equation or gradient calculation.
10. (4, 3), $6y + 7 = -\frac{1}{3}(x - 6)$: Find the equation of the line or interpret its slope.

Let me know which specific problem you’d like me to help with, or I can solve them step-by-step!

Would you like detailed solutions for any of these problems?

Here are 5 questions to consider based on the topics:

1. How do you find the equation of a line using a given point and slope?
2. What is the general formula for finding the equation of a line through two points?
3. How do you determine if three points are collinear?
4. What steps are needed to find the gradient (slope) of a line from its equation?
5. How do you graph a quadratic equation, and what features do you need to highlight?

Tip: When working with linear equations, the slope-intercept form $y = mx + b$ is a helpful format, where $m$ is the slope and $b$ is the y-intercept.
