Please help me out! i have a few more of these questions, about 3!

    y= -x -4

Step-by-step explanation:

the negative represents the line decreasing or going down negatively

the 2/5 represents the slope or rise over run (the down then right from point to point)

the -4 represents the y intercept where the line crosses the y axis when x=0

i just took the test, the correct answer is .. 31.5 in.

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
