Hi there! :)
Answer:
y = -2x + 3
Explanation:
We can write an equation in slope-intercept form. Use the slope formula to find the rate of change in the table:
![m = \frac{\text{rise}}{\text{run}} = (y_2 - y_1)/(x_2 - x_1)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/mv0f01wjhclcpvv5w0mywnj72c5z3j64nn.png)
Plug in values from the table:
![m = (5 - 7)/(-1 - (-2))](https://img.qammunity.org/2021/formulas/mathematics/college/4mbo4kn9w09yl3bmdbwmolno5j7kfa82tu.png)
Simplify:
m = -2 (rate of change)
Use a point from the table (-2, 7) and the slope to solve for the equation for the linear function:
7 = -2(-2) + b
7 = 4 + b
7 -4 = b
b = 3
Rewrite:
y = -2x + 3 is the equation for the linear function.
