Question

Use the graph above. find the slope and the y-int, then give the equation of the line y=mx+b

Answer 1

Answer: y = 2x + 4

Step-by-step explanation:

By looking at the graph, we can use rise over run to figure out the slope:

$\frac{rise}{run} = \frac{2}{1} = 2$

Next, to find the y-intercept, see the point where the line meets with the y-axis, which is at (0,4). Now, simply place those variables found into y=mx+b, where m is the slop and b is the y-intercept.

y = mx + b

y = 2x + 4
