Question

Identify the slope and y-intercept of this graph.

•
slope = 2, y-intercept = 1
slope = 2, y-intercept = 1
slope = 2, y-intercept = -1
slope = -2, y-intercept = -1

Identify the slope and y-intercept of this graph.

Answer 1

15. slope=-2

y-intercept=2

16. slope=2

y-intercept=1

Explanation:

ya kinda dub scalliwag, all you need to do is find the growth factor and starting point

Answer 2

Explanation:

Looking at the first graph, we see that if x increases from 0 to 1, y decreases from 2 to 0:

m = rise / run = -2/1 = -2

Arbitrarily choose the reference point (1, 0).

Then y = mx + b becomes 0 = -2(1) + b, where b is the y-intercept.

Then b = 2, and the desired equation is

y = -2x + 2
