Mathematics
1 answer:
shutvik [7]3 years ago

Answer:

y= 1/3 x +5

Step-by-step explanation:

To find the slope, we take two points

(0,5)   and (15,10)

The slope is found by the formula

m = (y2-y1)/ (x2-x1)

   = (10-5)/(15-0)

   = 5/15

   = 1/3

The slope is 1/3

The y intercept is found when x=0

When x=0  y=5

The slope intercept form of the line is

y=mx+b  where m is the slope and b is the y intercept

y= 1/3 x +5
