help!! i know that the equation for A is y=1/2x+3, but i need the standard form equation. I also need both the slope equation and standard form equation for B.

The number of hours per week that the television is turned on is determined for each family in a sample. the mean of the data is 37 hours and the median is 33.2 hours. twenty-four of the families in the sample turned on the television for 22 hours or less for the week. the 13th percentile of the data is 22 hours. approximately how many families are in the sample? round your answer to the nearest integer.

Are the corresponding angles congruent? explain why or why not.

Which shows the first equation written in slope-intercept form? 1/2 (2y + 10) = 7x
