Question

5. Which equation represents the linear relationship between and y shown in 6. Whic grap the cable 1 23 -3 -5 - 7 3. A. -*-2 B.y=-x+1 Cy-2x+1 D. 2-1

Answer 1

The equation that represents the linear relationship between x and y

From the above table

$\begin{gathered} \text{when x = 0 , y = 1} \\ \text{Option A } \\ y\text{ = 0 - 2} \\ y\text{ = -2 (wrong)} \\ \end{gathered}$

when x = 2 , y = -3

$\begin{gathered} \text{Option B} \\ y\text{ = -x + 1} \\ y\text{ = -2 + 1} \\ y\text{ = -1 (wrong)} \end{gathered}$

when x = 3 , y = -5

$\begin{gathered} \text{Option C} \\ y\text{ = -2x + 1} \\ y\text{ = -2(3) + 1} \\ y\text{ = -6 +1} \\ y\text{ = -5 (correct)} \end{gathered}$

when x = 4 , y = -7

$undefined$
