Question

Write the equation of the line, with the given properties, in slope intercept form. Slope=-8, through (-3,6)

Answer 1

y = - 8x - 18

the equation of a line in ' slope-intercept form ' is

y = mx + c (m is slope and c the y-intercept )

here m = - 8 ⇒ y = - 8x + c

to find c substitute ( - 3 , 6 ) into the equation

6 = 24 + c ⇒ c = 6 - 24 = - 18

y = - 8x - 18 is the equation
