Question

What is the equation of the line with a slope of 2 and a y-intercept of −4?

y = mx + b
m = 2 and b = −4
y = 2x − 4

I understand the concept but how do I know which kind of equation it asks for, standard form or slope intercept? For this question I know it's slope intercept but I ask for future reference.

Answer 1

You are absolutely right ;o

Answer 2

well when you have two points, use slope intercept. when it says AX+BY=C use standard

Answer 3

I know, but what I'm asking is how do I know that the question is asking for either one?

Answer 4

@LydiannAquino what exactly is standard form.... can u explain meh?

Answer 5

y=mx+b

Answer 6

and slope intercept form ?

Answer 7

y-y1=m(x-x1)

Answer 8

actually
u have slope which is represented by m =2 and the y intercept which is represented by ''b''
so the slope intercept form formula is
y=mx+b
so just put and get the answer which is y= 2x-4 but here it is asking about the equation line so if the question said to u write the equation of line in slope intercept form then u will write but if not the convert it into standard form
that is
2x -y-4=0 is the equation of line

Answer 9

Ok, Thank You.

Answer 10

have u got it ?

Answer 11

Yes.
