Question

A line is represented by the equation y = x + 2. Suppose the slope of the line was doubled and the value of the y-intercept was divided by 2. What is the equation of the new line? A.y=2x+1 B.1/2y=x+4 C.2y=x+1 D.y=1/2x+4

Answer 1

A.y=2x+1

Explanation:

y = x+2

This is in the form y= mx+b

where m is the slope and b is the y intercept

m=1 we are doubling it

m=2

The y intercept is 2, we are dividing by 2

2/2 =1

b=1

y = mx+b

y = 2x+1
