Question

Write the equation of this line in y= mx + b form:

Answer 1

y=5x+3

Explanation:

Slope: y2-y1 over x2-x1 so it will be 3-(-2) over 0-(-1) and the answer will be 5.

Y intercept: In order to find the y intercept it is necessary to replace the y an x coordinate in the equation: y= mx+b and replace 3=5(0)+b... simplifying would be 3=b

so the final answer would be y=5x+3

Answer 2

y = 2.5x + 3

Explanation:

y = mx + b

y = 2.5x + 3

As you can see, each unit is not 1, its 0.5. We need to go up 5 times, and so 0.5 times 5 gives us 2.5, and thats how i got my slope.

I got 3 as my y-intercept because it's were the line intersects the y axis.

Hope this helped!
