Me with these last two my teacher didn’t explain it really well

So since you know that this is a line you can use the slope intercept form which is y=mx+b. M being the slope and B being the y intercept. So for 5a. It is asking for the equation so you just plug in the numbers into y=mx+b.

y=5x-2

For 5b all you have to do is plug in 0 for y in the equation above.

So it will be 0=5x-2. So you simplify it.

Subtract 2 to both sides and you get -2=5x

THen divide by 5 on both sides to isolate the x and so you will get -2/5 =x.

So the answer would be the value of x when y is 0 is -2/5

I really hope that this helped you in some way. If you have any questions feel free to ask me. Have a great day :)

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
