Answer: y = -2/5x + 3
Step-by-step explanation:
The formula for a line is: y = mx + b.
<em>m</em> is the slope of the line. We calculate this by looking at how many units the line travels vertically over how many units the line travels horizontally, or rise over run. In this example, we can see that the line goes down 2 units for every 5 it goes to the right, meaning the slope is equal to -2/5.
<em>b</em> is the y-intercept, or where the line crosses the y-axis. In this example, the line crosses the y-axis at (0, 3) making the <em>b</em> value equal to 3.
Therefore, the equation for this line put together is y = -2/5x + 3.
I'm taking the same final test.
The answer is y= 1/4x - 5
How? Well in this case we are using the formula y= mx + b
Substituting it with the given point (8, -3) and the slope 1/4
it'll look like -3 = 1/4 (8) + b
Next we solve.
-3 = 1/4 (8) + b
-3 = 8/4 + b
-3 = 2 + b
-2 -3 = b
-5 = b
so we now we know that b = -5.
All we have to do is substitute that into the equation to get our final answer (this time, without the point 8,-3).
Our answer in the end is y = 1/4x -5
