Question

Write an equation in slope-intercept form of the line through point P(6, –1) with slope 4.
A. y + 1 = 4(x – 6)
B. y = 4x – 25
C. y = 4x – 1
D. y + 6 = 4(x – 1)

Answer 1

y-y1=m(x-x1)
that is equation for lne passing through (x1,y1) and has slope of m

given
(6,-1) and slope 4
(x1,y1)
x1=6
y1=-1
m=4


y-y1=m(x-x1)
y-(-1)=4(x-6)
y+1=4(x-6)
A is answer
