Answer:
Solution (1, 4)
Step-by-step explanation:
x = y - 3
x + 3y = 13
Substitute x = y - 3 into x + 3y = 13
y - 3 + 3y = 13
4y - 3 = 3
4y =16
y = 4
Substitute y = 4 into x = y - 3
x = 4 - 3
x = 1
Solution (1, 4)
The correct answer is 8.375
Answer:
Expression
Step-by-step explanation:
Hey there! I'm happy to help!
Let's think of this as the equation y=mx+b, where m represents the slope and b equals the y-intercept.
The y-intercept is where the line hits the y-axis. As we can see, it hits it at the y-value of zero. Therefore, our equation is just left as y=mx now because b is 0.
We want to find the slope now. This is known as the rise/run, or the y/x. This is basically saying how far up it goes for every one step to the right. If we go to the x-value of one, we see that the y-value is at a little bit less than one. We want to keep on moving to the right until the y-value is at a nice integer value (number without fractions).
If we keep on moving to the right, we see that at the x-value of 3, the y is at 2. This means that the slope is 2/3. And it makes sense! When we were looking at that value of 1, the y-value was less than one and looked like it was at about 2/3, or 0.666....
This will apply to all points on the line. Our y will always be 2/3 of what x is.
Therefore, the equation is y=2/3x
I hope that this helps! Have a wonderful day!
