Math Problem Statement
The table represents some points on the graph of a linear function.
Which function represents this relationship?
A
y=−3/2x+4
B
y=−3/2x−14
C
y=−2/3x−9
D
y=−2/3x−1y
Solution
To find the correct linear function that represents the relationship from a given table of points, we need to determine the slope () and the y-intercept () of the linear equation in the form .
Steps:
- Find the slope : The slope can be calculated using any two points and from the table using the formula:
- Determine the y-intercept : After finding the slope, substitute one point into the equation and solve for .
If you have the points from the table, please share them, and I can proceed with the calculations.
