How do you write an equation from a word problem when they give you two coordinate plots?

y-y1=m(x-x1)

x1 = the x value in the first coordinate
y1 = the y value in the first coordinate

m (slope, or rise over run) = (y2-y1) / (x2-x1)

To write an equation from a word problem when given two coordinate plots, you need to analyze the information provided and determine the relationship between the variables involved. Here are the steps to follow:

1. Understand the problem: Read the word problem carefully and make sure you understand what it is asking for. Identify the given information and what needs to be determined.

2. Examine the coordinate plots: Analyze the given coordinate plots and try to visualize the relationship between the x-values and y-values. Look for any patterns or trends in the data.

3. Determine the variables: Identify the variables involved in the problem. The x-values are typically represented by the independent variable, while the y-values represent the dependent variable.

4. Find the slope: If the coordinate plots represent a linear relationship, calculate the slope using the formula: Slope (m) = (change in y) / (change in x). Select two points on the plot and calculate the difference in the y-values and x-values respectively.

5. Write the equation: Once you have the slope (m), you can use the point-slope form of a linear equation: y - y1 = m(x - x1). Choose any of the points from the coordinate plots and substitute the values for x1, y1, and m into the equation. Simplify the equation if necessary.

6. Solve for the unknown: If the problem asks you to find a particular value or relationship, use the equation you derived from Step 5 to solve for the unknown. Substitute the given values into the equation and solve for the unknown variable.

Remember that these steps assume a linear relationship between the variables. If the relationship is nonlinear, you may need to use a different equation or approach to solve the problem.
