If a given data point is (1,4) and the line of best fit is y = 1.5x + 3.25, what's the residual value? Question 4 options:

A)

–0.75

B)

–0.25

C)

0.75

D)

0.25

If the model is good, then both points will check in the equation. Substituting 8 for x and 5 for y in the equation results in 56 – 50 = 3, which is not true. Therefore, the model is not good. Using (–12, –9) as a check results in –84 + 90 = 3. The constant value in the equation should be 6, not 3. In slope-intercept form, the y-intercept should be –3/5. Hope this helps!!! :)
