Simplify

To simplify the given expression, you start by opening  the bracket

Next, you perform arithmetic operations on like terms

The answer can be further simplified;

Factorize

Hence;

when simplified is equivalent to or

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

answer: it's upside down and i can't read it
