Answer:
y = 1.5x
Step-by-step explanation:
We are to find the equation of the line
The equation is expressed as y = MX+c
m is the slope
c is the intercept
Get the slope
Using the coordnate (10, 15) and (20, 30)
m = 30-15/20-10
m = 15/10
m = 1.5
Get the intercept
Substitute m = 1.5 and (10, 15) into y = mx+c
15 = 1.5(10) + c
15 = 15+c
c = 0
Get the equation
y = mx+c
y = 1.5x+0
y = 1.5x
Hence the required equation is y = 1.5x
