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 ...
