Question

Which equation correctly represents the line graphed below?

Answer 1

C. y=3/2 x + 12

Explanation:

lets find slope,

fr that first lets point out some coordinates passing the line: ( 0, 12 ), ( 2,15 )

now find slope using the equation : y -y1/ x - x1

= 15 - 12 / 2 -0 = 3/2

• use any coordinates now to find the equation of line using formula:

y - y1 = m ( x - x1 )

y - 12 = 3/2 ( x - 0 )

y -12 = 3/2 x - 0

y = 3/2 x + 12

Therefore, y = 3/2 x + 12 is the equation of the line.
