Answer:
x = 8, y = 4
Step-by-step explanation:
x = 3y-4
2x - 8 = 2y
x - 4 = y
x = y + 4
substitute top equation to this equation
3y-4 = y+4
2y = 8
y = 4
now substitute this into second equation
x = y + 4
x = 8
check answer with first equation
x = 3y-4
8 = 3(4) - 4
8 = 8; correct
Answer:
The slope is -1/3
Step-by-step explanation:
y = -1/3x + 1/4
This equation is written in slope intercept form
y = mx+b where m is the slope and b is the y intercept
The slope is -1/3 and the y intercept is 1/4
