Question

Write an equation in point-slope form of the line through the given point of the given slop?

3.(5,1);m= 1/3
4.(-2,3);m= -2

Answer 1

point slope form : y - y1 = m(x - x1)
(5,1) x1 = 5 and y1 = 1
slope(m) = 1/3
now we sub
y - 1 = 1/3(x - 5) -- point slope form
=======================
y - y1 = m(x - x1)
(-2,3) x1 = -2 and y1 = 3
slope(m) = -2
now we sub
y - 3 = -2(x - (-2)
y - 3 = -2(x + 2) -- point slope form

Answer 2

thank you! help me with more ?

Answer 3

lets see what ya got

Answer 4

y=3/4x+5
y+4=1/3(x+6
