Answer:
y = (1/4)x - 1
Step-by-step explanation:
Start with the general slope-intercept form: y = mx + b. Subst. -1 for b and (1/4) for m. Then,
y = (1/4)x - 1
Answer:
x = 2
y = -3
z = 4
( 2 , -3, 4 )
Step-by-step explanation:
x + y + z = 3 ---- i
x – y =5 ---- ii
y - z = -7 ---- iii
ii + iii
x - z = -2 ---- iv
i + ii
2x + z = 8 --- v
iv + v
3x = 6
x = 2
x=2 substitute for v
z = 4
x =2 substitute for ii
y = -3
