Question

1Which equation represents a line that has a slope of 3 and passes through point (-2, 1)?, ?o y-3x-153O y-*x+1

Answer 1

The given slope is 3, and the given point is (-2, 1).

To find the equation of the line, we use the point-slope formula.

`y-y_1=m(x-x_1)`

Now, we replace the slope and the given point.

`\begin{gathered} y-1=3(x-(-2)) \\ y-1=3x+6 \\ y=3x+6+1 \\ y=3x+7 \end{gathered}`

Therefore, the equation of the line is

`y=3x+7`
