19. write an equation for a line with a slope of 1
passing through the point (4,3).

y-3=1(x-4) or y=x-1

Step-by-step explanation:

when you have the slope and the point you can use point slope form.

if you have point (a,b) and slope m it would go y-b=m(x-a).

exa:

)

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
