Question

Is "y = 0.860x + 3.302" a function? Explain why.

Answer 1

Yes.

General Formulas and Concepts:

Algebra I

Slope-Intercept Form: y = mx + b

• m - slope
• b - y-intercept

Explanation:

Any line that follows slope-intercept form will be a function.

If we graph this line, we can see that each x-value has its own y-value and it passes the vertical line test.

∴ y = 0.860x + 3.302 is indeed a function.
