When graphing the first line of the system of equations, what do you plot first on the coordinate plane?

y = x - 4
y = - x + 6

awnser-

a. slope of -4

b. y intercept of -4

c. slope of 1

d. y intercept of 1

Option B, y intercept of -4

Step-by-step explanation:

Option A is incorrect because you cannot use the slope because you don't know where or what point to start from.

Option B is correct because the first thing you do is plot the y intercept of -4 and then you find the slope of the line.

Option C is incorrect because you cannot use the slope because you don't know where or what point to start from.

Option D is incorrect because that is the wrong y intercept.

 Option B, y intercept of -4

t=-p/5+20

Step-by-step explanation:

p=100−5t

Swap sides so that all variable terms are on the left hand side.

100−5t=p

Subtract 100 from both sides.

−5t=p−100

Divide both sides by −5.

−5t/5 = p - 100/-5

Dividing by −5 undoes the multiplication by −5.

t = p - 100/-5

Divide p−100 by −5.

t=-p/5+20
