Question

lect the correct answer.The equation of a line is y=-3x - 2. What are the slope and the y-Intercept of the line?

Answer 1

Given the equation of a line as shown below :

`y=-3x-2`

To determine the slope and the y - intercept of the line, compare the equation with straight line equation

`y\text{ = mx+c}`

After comparing the equation of a line

`\begin{gathered} m\text{ = slope} \\ c\text{ = y-intercept} \end{gathered}`

`\begin{gathered} y\text{ = -3x-2 } \\ y=mx+c \\ m\text{ = -3 } \\ c\text{ = -2} \end{gathered}`

Therefore slope = -3 and y - intercept = -2
