Answer:
(0, -5), (4, -2), (-16, -17)
Step-by-step explanation:
I attach your full question in the image below
The equation is
3x-4y-8=12
Which can be rewritten as
3x-4y =12 +8
3x-20 = 4y
y = (3/4)*x - 5
We need to check each individual case
(0,-5)
y = (3/4)*(0) - 5
y = -5
True
(4,-2)
y = (3/4)*(4) - 5
y = -2
True
(8,2)
y = (3/4)*(8) - 5
y = 1
False
(-16,-17)
y = (3/4)*(-16) - 5
y = -17
True
(-1,-8)
y = (3/4)*(-1) - 5
y = -23/4
False
(-40,-34)
y = (3/4)*(-40) - 5
y = -35
False
(0,-5) (4,-2) and (-16,-17) are the solutions
Answer:
Start at the origin and go to the left by one and go down by 4
Step-by-step explanation:
The x coordinate relates to the horizontal axis and the y axis refers to the vertical axis.
Before we start graphing we must always begin at the origin (0,0)
Since the x value is -1 we have to move left by 1 on the x axis
We would move to the left one value because negative is on the left side
For the y value, we would have to move 4 down on the y axis because this number is also negative.
So your graph should look like this
Hope this helps :)
