y=mx+b
we know slope so m=4 and we know the x and y coords so x=3 and y=7
y=mx+b
7=4(3)+b
7=12+b
7+12=b
b=19
therefore
y=4x+19

A.
y – 7 = 4(x – 3)
B.
y – 7 = 4(x + 3)
C.
y + 7 = 4(x + 3)
D.
y + 7 = 4x – 12

\[\frac{ y2y1 }{ x2x1 } is slope here\]

as we already have slope =4 so no need to go for slope
and (x1,y1 ) are (3,7) @zobobozo
