Question

Which equation describes the line that passes through points (2,5) and (0,9)?

Answer 1

Answer:

y = -2x+9

Step-by-step explanation:

We first need to find the slope

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

   = (9-5)/(0-2)

   = 4/-2

   = -2

We will use the slope intercept form of a line

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

y =-2x+b

We know that 9 is the y intercept since x is equal to zero

y = -2x+9
