Question

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​

Answer 1

Answer: Option b, y-interception of -4

Answer 2

Option B, y intercept of -4

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.

Answer: Option B, y intercept of -4
