D. y = 1/2x -3


What Is The Equation Of This Line A Y 2x 3 B Y 12x 3 C Y 2x 3 D Y 12x 3 class=

Sagot :

A. y = 2x - 3

The slope is positive 2 and the y-intercept is -3
Therefore your answer is A.

Answer:

y=2x-3

Step-by-step explanation:

y=mx+b

b= -3 --> This is because it intercepts (pass through) y at -3.

(y2-y1)/(x2-x1)  

Note: Pick two spots where it directly goes through.

(-3-3)/(0-3)

(-6)/(-3)  

2 --> When a negative divides a negative it becomes positive. Also, whenever the line increases from the left to the right it is positve. When it increases from the left to the right, it is negative. This example is positve.
