Answer:
slope = 1
y-intercept = 5
Step-by-step explanation:
change in y-values = 1
change in x-values = 1
slope = 1/1 or 1
to find the y-intercept ('b'), select an ordered pair: (1, 6)
use the slope-intercept formula and solve for 'b':
6 = 1(1) + b
6 = 1 + b
5 = b
x=3 y=4
8x+9y=60 + 2x-9y=-30
10x=30
x=3
y=4
