) Himari is solving the equation 4 (x - 3) = 16. Her first step is 4x - 12 = 16. Which step could be the next step? Select all that apply.
1) 4x -12 + 12 = 16 + 12
2) 4x - 12-(-12) = 16 - (-12)
3) 1/4 • (4x - 12) = 16 • (1/4)
4) 4x/4 - 12 = 16/4
5) 4 • (4x - 12) = 16 • 4

it would be 1 and 2

Step-by-step explanation:

It would be number two because to negatives make a positive like this.

16-(-12) is the same as 16+12 and 12-(-12) is the same as 12+12

4(x-3)=16

4x-12=16

4x=16+12

4x=28

x=7

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
