Question

The equation of the line the point (-1,3) and perpendicular to the line x+2y=-6 is

Answer 1

what is the slope of x+2y=-6?

Answer 2

3

Answer 3

No...put it in slope intercept form
x+2y=-6
2y=-x-6
y=-1/2x-6

now can you see what the slope is

Answer 4

is that how u suppsoe to write it out

Answer 5

you need the slope of it to figure out the slope of the other line. the slope of x+2y=-6 would be -1/2. perpendicular lines have negative reciprocal slopes of each other so the other lines slope would be 2.

now use
y-y1=m(x-x1) to get the equation of the line

Answer 6

x-2y=5
