Identify the equation whose graph has a slope of 2 and a y-intercept of -3.

Identify the equation whose graph has a slope of 2 and a y-intercept of -3.

2x + y = -3
2x - y = 3
2x + y = 3
2x - y = -3


Best answer 10pts...


Can you explain it to me?? I am really having a tough time on this :(((

I think the answer is D ...?

Your answer is B

First put into standard slope-intercept form, y= mx + b
y = 2x - 3

Your slope is m, which is 2

Now to find your y intercept, plug in x=0
which gives you -3

hey!

an easy way to do this, is to first find a point in the graph

if you draw you get the following point with the help of the slope and y intercept given: (1,-1)

remember the equation for y intercept:

y-y1=m(x-x1)

y--1=2(x-1)
y+1=2x-2
y=2x-3 or 2x-y=3

m=2 b=-3 So put these into the formula y=mx+b
y=2x+ (-3) or
y=2x-3 Now which of those equation can to transformed
into this?
The second one 2x-y=3
2x-3=y or y=2x-3 Hint: Put your equations into the form y=mx+b where m is
the slope and b is the y-intercept

it is D
