Calculate the answer when the largest prime number that is a factor of 28
is multiplied by
the smallest prime number that is a factor of 15

21

Step-by-step explanation:

7 is the largest prime number of 28

3 us the smallest prime number of 15

7 × 3 is 21

Convert to slope intercept form which is y=mx+b where m=slope and b=y-intercet

basically, we want only 1 y on one side so
3y+2x=12
subtract 2x from both sides
3y=12-2x
divide both sides by 3
y=4-2/3x
y=-2/3x+4
y-intercept=4
so in (x,y) form
the y intercept is when the line crosses the y axis or when x=0 so
(0,4) is thea nswer


a is the answer
