Question

what is an equation of the line in point-slope form that passes through the given point and has the given slope? point: (8,-8) slope 3

Answer 1

the general format of a straight line is
y = mx + b
where
m = slope
and
b = intercept

since the slope is 3
u can write the equation of the line as
y= 3x + b
now all u want is to find the value of b...

to find b u can use the coordinates (8 , -8)
this coordinates means that the line will pass through a point where
x = 8 and y = -8
plug these values to the equation
y= 3x + b
then u will get
-8 = (3x8) +b
-8 = 24 + b
b = -32

that's it!!
then u will have the equation of the straight line as
y = 3x -32

hope this will help ya:)
