Please help me with question 3 here

Answer 1

Answer:

y = (1/2)x + 2, in which 1/2 represents a fraction.

Step-by-step explanation:

Remember your formula y = mx + b; where m is the slope, and b is the y-intercept.

Now, simply look for the y-intercept (should be 0, 2), and plug in the x value in for the b.

The equation is now y = mx + 2.

For the next part, you'll find the slope; forewarning is that it doesn't matter how you do it, as long as you do it right. You can either use the slope formula, but I like to do rise over run. They're the same thing. If you don't know what rise over run is, look it up, it's pretty easy to understand. If not just do the slope formula.

Anyways, you need to grabs two different points that plot on the line; let's say (0, 2) and (2, 3). If you do the formula it should be (3 - 1) / (2 - 0). This will get you your 1/2.

Plug that into m, and your formula should be y = (1/2)x + 2, where 1/2 is a fraction.
