Determine the slope and y-intercept of the line represented by the equation.
y + 3 = 3 ( x − 7 )

slope:

y-intercept: (0, )

slope = 3

y - intercept = ( 0 , -24)

Step-by-step explanation:

The equation of a line in slope- intercept form is given as :

y = mx + c

Where m is the slope and c is the y - intercept.

What we need to do is to write the equation given in this form ,that is

y + 3 = 3 ( x - 7 )

Expanding the R.H.S , we have

y + 3 = 3x - 21

subtract 3 from both sides

y = 3x - 21 - 3

y = 3x - 24

comparing this with the formula , we have

slope = 3

y - intercept = ( 0 , -24)
