Answer:
a. y = x - 2
Step-by-step explanation:
y = a.x + b
from the graph: x = 0, y = -2 --> b = -2
x = 2, y = 0 --> 0 = a.2 -2 --> a = 1
(5,-2)(-3,4)
slope = (4 - (-2) / (-3 - 5) = 6/-8 = - 3/4
y = mx + b
slope(m) = -3/4
use either of ur points...(5,-2)...x = 5 and y = -2
now we sub and find b, the y int
-2 = -3/4(5) + b
-2 = -15/4 + b
-2 + 15/4 = b
-8/4 + 15/4 = b
7/4 = b
so ur equation is : y = -3/4x + 7/4 <==
D
7•4 =28, -5•0 =0... 28+0=28
