Please help me

OpenStudy (tamara7301):

What do u need help☺☺

OpenStudy (freemap):

Which equation represents the line shown?

OpenStudy (tamara7301):

C

OpenStudy (tamara7301):

That's what I think

Directrix (directrix):

(2,2) and (0,3) are points on the line. That gives a slope of -1/2. That may eliminate some options. I haven't looked yet.

OpenStudy (freemap):

Thats what I thought as well.

OpenStudy (tamara7301):

Great

OpenStudy (tamara7301):

Do u need anymore help?

Directrix (directrix):

Y = (1/2) x + 3 is not correct

OpenStudy (freemap):

so that eliminate c because c its just 1/2 instead of -1/2?

Directrix (directrix):

Yes. Also, the point (2,2) is not on that line.

OpenStudy (tamara7301):

No its C

OpenStudy (freemap):

So we know that it'll have to be d because of the -1/2 slope

OpenStudy (tamara7301):

Cause c is -1/2

OpenStudy (freemap):

@Tamara7301 its just 1/2

Directrix (directrix):

Correct. That is the only -1/2 slope. Also, the two points I read off the graph are on that line at D.

OpenStudy (tamara7301):

Isn't -1/2 or am I blin

OpenStudy (tamara7301):

Oh sorry

OpenStudy (freemap):

thats okay

OpenStudy (freemap):

Thank you

OpenStudy (tamara7301):

Ok well sorry for the confusion bye

Directrix (directrix):

Look at the given line. Moving from left to right along the x axis, the values of y are decreasing which is indicative of a negative slope.
