Question

4) Slope = 0 and y-intercept (0, -1)

5) Slope = -1 and y-intercept (0,4)
Type answer here

Find the equation for each slope

Answer 1

4.)
`y=-1`

5.)
`y=-1x+4`

Explanation:

Use the slope-intercept form for each:

`y=mx+b\\\\m=slope\\\\b=y-intercept\\\\(x,y)`

The y-intercept happens when x is equal to zero, so when you have the point (0,y), plug in the y-value as the y-intercept.

4.) Insert the appropriate values in the equation:

`y=0x-1`

Simplify. Any number multiplied by 0 is 0, so:

`y=0+-1\\\\y=-1`

5.) Insert the appropriate values:

`y=-1x+4`

This cannot be simplified further.

:Done

Answer 2

Explanation:

So, lets do the first one.

Slope = 0 and y-intercept is (0, -1)

The y intercept is the second number in the pair because it's the y value

we can switch this to,

y = mx + b

so,

y = 0x - 1

for the first one.

The second one has a slope of -1 and a y intercept of (0,4)

like I said the y intercept is the second number in the coordinate pair,

so,

y = -1x +4

Hope this helps!
