Question

the equation for the line of best fit is ( y = -x + 25 ). according to the equation, which of these statements is true?
liam would probably type about 25 words incorrectly after 10 weeks of the typing class.
liam probably typed about 25 words incorrectly at the start of the typing class.

Explanation:

Step1: Analyze the linear equation

The equation of the line is \(y = -x + 25\), which is in the slope - intercept form \(y=mx + b\), where \(m=-1\) (slope) and \(b = 25\) (y - intercept).

Step2: Interpret the y - intercept

The y - intercept \(b\) represents the value of \(y\) when \(x = 0\). In the context of the problem, \(x\) is the number of weeks since the class started. When \(x = 0\) (at the start of the class), \(y=-0 + 25=25\).

Answer:

Liam probably typed about 25 words incorrectly at the start of the typing class.
