Answer:
y=3/4x-2
Explanation:
The first thing you would do is you would get a graph.
Now write down the point (8,4) (remember to label)
Remember (8,4) is where x is 8 and y is 4
A slope of 3/4 is also known as rise/run. This means in this problem you would rise 3 and move to the right 4. If the slope were negative you would do the opposite direction. For example -1/2 would be go down one move right four.
*You should graph points above and below your point
After that you would go from the point (8,4) and rise 3 and move over to the right 4. This gives you the point (12,7).
Write down that point.
Next you would do another point. So that means you could go down 3 and move 4 to the left which gives you the point, (4,1)
*I recommend having more than two points, but only two points are needed to make a line.
Now you can find the y-intercept with your graph and put it on your equation.
if you want to do it without a graph you need to know this formula.
y=mx+b where m is the slope and b is the y intercept.
Next, put in the equation what you already know so m=3/4.
That give you y=3/4x+b
Next, to find the y intercept plug in the point (8,4). This way you can find the y intercept.
this gives you: 4=3/4(8)+b
Solve for b.
b=-2 so that your y intercept.
So your equation is: y=3/4x-2.
*I recommend checking my work, but this is what I got.
Hope this helped!
