Question

What is the equation??

Answer 1

I believe the correct equation would be y = 3x + 4.

Explanation:

To find the slope (or m), you put the rise (y-axis) over the run (x-axis). You would then put it in Slope-Intercept form: y = mx + b.

Starting at (0, 4), you rise up 3, and run 1. The slope (m) would be 3/1, which is the same as 3.

So far you have y = 3x, which is not the full equation.

You would then look for the initial value (or y-intercept) of the linear equation. Start at the origin of the graph - (0, 0) - and rise up until you get to the first point, (0, 4). You rise up 4, so the initial value is 4.

Your ending equation would be y = 3x + 4.

Hope this helps,

Answer 2

It is 3x +4

Explanation:

1. The equation is starting at x=0 so, let's calculate the equation.

3 x 0 + 4= 4

2. The equation goes up 3 digits on y per each digit of x so, we introduce that y is 3 times the value of x + the starting point (+4)

f(x)=3x+4
