Question

typing tests

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 equation \(y = -x + 25\)

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

Step2: Interpret the y - intercept

In the context of the problem, when \(x = 0\) (start of the typing class, since \(x\) represents weeks since class started), \(y=-0 + 25=25\).

Answer:

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