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 (mm) and the y-intercept (bb) of the linear equation in the form y=mx+by = mx + b.

Steps:

  1. Find the slope mm: The slope can be calculated using any two points (x1,y1)(x_1, y_1) and (x2,y2)(x_2, y_2) from the table using the formula:

m=y2y1x2x1m = \frac{y_2 - y_1}{x_2 - x_1}

  1. Determine the y-intercept bb: After finding the slope, substitute one point (x,y)(x, y) into the equation y=mx+by = mx + b and solve for bb.

If you have the points from the table, please share them, and I can proceed with the calculations.

Tip: Always check for consistent differences between y-values to confirm a linear relationship when given a table of points.
