7.4

Graph and, if possible, determine the slope.

30. x = -4

Slope x = - 4 is infinity

34. f (x) = 2

The standard form of line y= mx + c , where m is the slope and c is the intercept

Here the function can be written as y = 0x+2

Thus slope =0

20. Graph using the slope and the y -intercept.

F (x) = x + 3

Slope = 2/5

Y intercept = 3

Determine ...
