Find the equation of the line.
Use exact numbers.

y=2x+4

Step-by-step explanation:

From the graph, we already know what the y-intercept is. The line crosses the y-axis at (0,4). Therefore, 4 is our y-intercept.

For the slope, we can take any 2 points on the graph and then use the formula to find slope. Let's use (1,6) and (2,8).

Now that we know the slope, we can fill in our slope-intercept equation.

y=2x+4

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
