Question

Kiara said the line with equation 28x – įy = -20has a slope of 28. What mistake did Kiara make?

Answer 1

Kiara's error is to say that the slope is 28 when the equation does not have that form y = mx + b

Explanation:

The form of the equation in the slope and y-intercept form is as follows

`\begin{gathered} y=mx+b \\ \text{where m is the slope and b is }y-\text{intercept} \end{gathered}`

The value that accompanies x is the value of the slope, but if and only if the equation is in this form.
