Question

PLEASE HELP!!!!!

What is the equation of a line that is perpendicular to -x+2y=4 and passes through the point (-2,1) ?

Write the equation -x+2y=4 in slope-intercept form

Identify the slope of the line represented in part a.



What is the slope of the line perpendicular to the line in steps a and b?



Write the equation of the perpendicular line in slope-intercept form.

Answer 1

y=1/2x+b

Explanation:

-x+2y=4 = 2y=x+4

2y/2=(x+4)/2 = y=1/2x+2

1=1/2(-2)+b = 1=-1+b = 2=b

y=1/2x+2

slope= 1/2

y-intercept= 2
