The equation is in the # y = mx +b# y intercept form. where
#m =# the slope ( think mountain slope ski resort)
#b =# the #y# intercept ( think beginning pony)
The equation # y= 4x + 8#
#m = 4/1color(white)(000)# The change in #y# is 4 and the change in #x# is 1
#b= 8color(white)(000)# The line crosses the #y# axis at #( 0,8)#
Start at the y intercept 8 make a point at #( 0,8)# Then use the slope
Go up 4 on the #y# axis
# 8+ 4 = 12# The #y# value of the second point is 12
Go over 1 on the #x# axis
# 0 + 1 = 1# the #x# value of the second point is 1.
make a second point at #( 1,12)# Connect the dots.
