Question

I really need help on this question pls do part a on a graph and can u pls do part b thx.

Answer 1

Answer: When y=1, x=
`(1)/(2)`

It will be a point with the coordinates (
`(1)/(2)`, 1)

Explanation:

- Start plotting points from the y-intercept, in this case, -1.

- Since the function is written in the form y=mx+b, where the slope is b which is in this case 4. Meaning to say that from the y-intercept -1 you have to go 4 units up and 1 unit right.

- Continue plotting 2 or 3 points, then connect them with a straight line.

- For the value of x when y=1, we can substitute y with 1 and solve the equation for x.

1=4x-1 (Add 1 to both sides)

2=4x (Divide by 4)

`(1)/(2)`=x Write the solution.
