Question 1123980: Hello, I'm personally trying to help my daughter with a Math problem, however, Math is just not my best subject, therefore, my hopes are you are able to help me.
The question is:
What is an equation of the line in slope-intercept form?
m=3 and the y-intercept is(0,4)
A. y=4x+3
B. y=-3x+4
C. y=4x-3
D. y=3x+4

You can put this solution on YOUR website! What is an equation of the line in slope-intercept form?
m=3 and the y-intercept is(0,4)
---------
Slope-intercept from is y = mx + b where m = slope and b is the y-intercept
--------
y = 3x + 4

Ordinarily you would use the slope-intercept form: y = mx + b, or the point-slope form:  to determine the equation.
However, in this case, it's much easier to use the FORMER, as the point (0, 4) indicates the y-intercept POINT of the equation, and so, "b" = 4.
Therefore, with y = mx + b, we just substitute 3 for m or the slope, and 4 for b. This results in: 
That's it!!
