1) Select the linear function that is perpendicular to the following: y = 4x + 12

Step-by-step explanation:

slope of line y=4x+12 is 4

slope of line perpendicular to y=4x+12 is -1/4

eq. of perpendicular line or perpendicular linear function is y=-1/4x+b  where b is the y-intercept.

In general, the students increased their standardized math scores from 5th grade to 7th grade. The students might be more familiar with the exam and they have learned more in their math classes.
