Question

which of the following is true for this table?
X=0, -1, 2, 1
y=4, 6, 0, 2

A. The line has a positive slope
B. The X-intercept is (2,0)
C. y= -1/2x+4

Answer 1

First you have to find the formula of the table in slope-intercept form:
y = mx +b
M = slope
B = y - intercept.

Answer 2

For the (x, y) simply choose a given point and substitute it in.

Answer 3

To find the slope (m) use the slope formula

y2 - y1
------
x2 - x1

Answer 4

which one do u think i right?

Answer 5

I can't answer that for you. I'm just here to help.

Answer 6

To be clear, C is not the right answer. 50/50 shot.

Answer 7

If you plot the points on the graph like (0,4),(−1,6),(2,0),(1,2), you will find that the graph doesn't have a positive slope, but a negative one.

Answer 8

Even if you graphed it, you will find the x - intercept at (2, 0) and the y - intercept at (0, 4)!

Answer 9

Please medal if you think I'm right. :)
