What’s the right process used to achieve steps 1-4

x=1.875

Step 1: you need to multiply the brackets.

-2(5x+8) = -10x-16

-10x-16=14+6x

Step 2: you want to put the x on one side, so take away 6 x from both sides

-10x-6x=-16x, 6x-6x=0

-16x-16=14

Step 3: add 16 to both sides so the whole numbers are on one side

-16+16=0, 14+16=30

-16x=30

Step 4: finally, divide the whole by the number of x, so 16

x=1.875

If you need to round it to a significant figure:

1 Sf: x=1.9

2Sf: x=1.78

3 Sf: the final answer only has three figures after the decimal.

Step-by-step explanation:

Hope this helps, have a wonderful day!

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

15.36 per mile

but forgot to round

i am pretty sure
