Prime number is only divisible by 1 and itself. ... No other whole numbers can multiply together to make 11. 15 is not a prime number because the factors of 15 are 1, 3, 5 and15 ( ). 15 has more than 2 factors, so it is not a prime number. true or false

15 is not a prime number - True

This is because 15 has other factors than 1 and 15, 3 and 5. Because it has other factors, it is not a prime number. An example of a prime number would be 7, 5, or 11, which are prime numbers because their only factor is 1 and itself.

Hope this helps!! :)

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
