Find the equation, in standard form, of the line that passes through (0,5) and has slope -3.

also, this one even though it's similar, I still had trouble:

Find the equation in standard form of the line that passes through (2, 7) and has slope 1/4.

Thank y'all in advance!

Starting with y = mx + b form

y = -3x + b sub in the point to calc 'b'

5 = -3(0) + b b = 5

y = -3x+5

y + 3x = 5 in standard form

y = 1/4x + b

7 = 1/4 (2) + b b = 6 1/2

y = 1/4 x + 6 1/2

y - 1/4 x = 6 1/2
