Use the point on the line and the slope of the line to find three additional points that the line passes

through. (There is more than one correct answer.)

Point Slope

(-8, 7) mis undefined

(x, y) = ( )

(x, y) = ( )

(x, y) = ( )


Find the slope and the y-intercept (if possible) of the line. (If an answer is undefined, enter

UNDEFINED.)

y= 7x+7

slope

y-intercept (x, y) = ( )


Find the slope and y-intercept (if possible) of the line. (If an answer is undefined, enter UNDEFINED.)

x+ y= 10

slope

y-intercept (x, y) = ( )

It can be shown that the line with intercepts (a, 0) and (0, b) has the following equation.

Use this result to write an equation of the line.

x-intercept: (8, 0)

y-intercept: (0, 9)


Sketch a graph of the equation.

x+ 3y+ 3= 0
