Fill in the missing value and calculate m (the slope): x f ( x) 2 −1 4 −2 5 2. Find the equation of the given linear function: x f ( x) −6 1 −3 2 0 3 3 4 3. Decide which of the two given functions is linear. x f ( x) g ( x) −10 −1.5 −9 0 0 −4 10 1.5 1 20 2.5 6 30 3.5 11 4. Find the slope of the given line, if it is defined. (a) y = − 2x −1 3 (b) 8 x − 2 y = 1 5. Graph the given equation: (a) y − 1 x = −2 4 (b) 2x − 3y = 6 6. In the following figure, estimate the slopes of all line segments: 4. A linear equation whose graph is the straight line with the given properties. 3⎞ 1 ⎛ Through ⎜1, − ⎟ with slope (a) 4⎠ 4 ⎝ (b) Through (1, − 4 ) and ( −1, −1) ...
