Show work please!!!
Thanks sooo much!
what is the equation of the line that has slope of 2 and y-intercept of -3?
A. 2x+y=-6 B. -4x+2y+-6 c. 2x+y+3 D. 4x+2y+0
Thanks! :D

y = mx + b = 2x - 3
Edit: y = 2x - 3 , is the slope-intercept form of the equation of the line asked for in this case.
Now the equation of the line in standard form is defined as either:
Ax + By = C , or: Ax + By + C = 0 => Notice that since C is constant its sign is written as positive for general form.
So in this case if we convert to standard form, we get:
y = 2x - 3
2x - y - 3 = 0 => where: A = 2 , B = -1 , C = -3
None of the options A-D match , C) 2x + y + 3 => is close but wrong , so no cigar.
Correct answer:
y = 2x - 3 => in slope-intercept form
or:
2x - y - 3 = 0 => in standard form
hence: All of given options: A - D are incorrect.
