How can you write an equation for the lines satisfying these conditions:
Passing through the point (0,4) and having a slope of 3??
Please explain to me and show all work!
Well the equation of a line is y=mx+c
Where m is the gradient (slope) and c is the y-intercept.
you are told what m is. Subtitute this into the equation, you get y=3x+c.
Finally sustitute in the (x,y) = (0,4) into y=3x+c to solve for c, then you are finished.
