A line has a slope of 1 and passes through the point (-8, -7). What is its equation in slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.

y = x + 1

Step-by-step explanation:

y = 1x + c

-7 = 1(-8) + c

-7 = -8 + c

-7 + 8 = c

1 = c

y = 1x + 1 or

y = x + 1

y+8=m(x+7)

hope this helps:

I used this formula y-y1=m(x-x1)

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
