Question

SOMEONE, PLEASE ANSWER THESE QUESTIONS!!!
Find the y-intercept for both linear functions.

Answer 1

Below

Explanation:

The y-axis intercept occurs when x = 0

so the first one is y = 21 ( this is the value when x = 0 from table)

the second one shows every 4 increase causes a 3 decrease in y

so every 4 DECREASE in x causes a +3 INCREASE in y

decrease x = 4 to x = 0 increase y = 6 to y = 9
