Question

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

Answer 1

Answer:

Step-by-step 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!

Answer 2

Answer:

4.) $y=-1$

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

Step-by-step 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.
