I need help for #4 (an explanation would be great)

15 square root of 6i

explanation:

square root of -54 can be re written as square root of -1 and square root of +54, the square root of -1 is basically i, and then the square root of 54 can be written as 9*6 and square root of 9 is 3

3 * 5 (which was outside the square root (see image) = 15 and square root of 6 is left along with the i

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

yes   because as the functions are graphed they eventually will intersect unless otherwise
