The slope will be the number that always sits next to x. So the slope in this case is 3/1. Which is rise over run. If it was a fraction, like 1/3, that would mean that the slope is rise one, run three.
If you want to find the y-intercept, you do that by putting a zero in for x, so you want to find the point that the line intersects the y-axis. So x would be zero, and wherever that point is is the y-intercept. In this case:
y = 3x - 1

y = 3(0) - 1

3 times 0 is zero

y = - 1 So, the y-intercept is - 1, or (0,-1)


To sketch the graph, you just place any number in for x or y (x is easier in this case), and solve it.
For example, I am going to say that x equals two.

y = 3(2)-1

y = 6-1

y = 5

So, your point to put on the graph would be (2,5) (x,y)

Which equation can be used to solve x/8 = 5? (ANSWER AND YOU GET 50 POINTS)
Ray Of Light [21]

Answer:

<h3>A. x=5*8</h3>

Step-by-step explanation:

Isolate the term of x from one side of the equation.

\sf{\dfrac{x}{8}=5 }

<u>First, you have to multiply by 8 from both sides.</u>

\Longrightarrow: \sf{\dfrac{8x}{8}=5*8 }

<u />

<u>Solve.</u>

<u />

<u>Multiply the numbers from left to right.</u>

5*8=40

\Longrightarrow: \boxed{\sf{x=40}}

<u>Therefore, the correct answer is "A. x=5*8".</u>

I hope this helps. Let me know if you have any questions.
