Jawapan:

# y = 5x-6 #

Penjelasan:

kami akan gunakan ## y = mc + c #

# m = "kecerunan / cerun (http://socratic.org/algebra/graphs-of-linear-equations-and-functions/slope)" #

# c = "y-intercept" #

# m = (Deltay) / (Deltax) = (y_2-y_1) / (x_2-x_1) = (4-6) / (2-0) #

# m = (4 + 6) / 2 = 10/2 = 5 #

#:. y = 5x + c #

# "untuk" (0, -6) #

-6 = 5xx0 + c #

# => c = -6 #

# y = 5x-6 #
