Identify the following.:
x : y
-10: 30
-5: 20
0: 10
5: 0

find y intercept (b):
slope(m):
equation:

Step-by-step explanation:

pick any 2 points from ur table...I will use (0,10) and (5,0)

slope(m) = (y2 - y1) / (x2 - x1)

(0,10)x1 = 0 and y1 = 10

(5,0)x2 = 5 and y2 = 0

now we sub and find the slope

slope = (0 - 10) / (5 - 0) = -10/5 = -2

now we use y = mx + b

slope(m) = -2 < ur slope

pick any point on ur table...I will pick (0,10)x = 0 and y = 10

now we sub and find b, the y int

10 = -2(0) + b

10 = b (0,10) <=== ur y intercept

so ur equation is y = -2x + 10 <=== ur equation
