Question

Find the equation of the line. Use exact numbers

Answer 1

y= 3x + 3

Explanation:

From the graph we get 2 points: (-1,0) and (0,3)

(0,3) tells us that b = 3

and we use the equation
`(y1-y2)/(x1-x2)` to calculate m

m =
`(3-0)/(0- (-1))` = 3/1 = 3

so plugging m and b into y = mx + b gives us

y = 3x + 3
