Question

Pararllel to y=1/2x+9 going through the point -4,2

Answer 1

2= .5(-4) + b
2= -2+b
add 2 to both sides
4 = b
then y=1/2x+4

Do you get how to do it now?

Answer 2

Since the two lines are parallel, their slopes are same i.e. 1/2 ( Equation of line is of the form y=mx+c, where c is the y intercept)
Now plug in the values of x and y you have got in the equation y=(1/2)*x+c and find the value of c which is 4.
Now you have the equation of the line as y=(1/2)*x+4

Answer 3

hmmm what's the slope of y=1/2x+9 ?
