Question

Write the equation of the line that has a slope of ½ and a y-intercept of -2.

Answer 1

Answer (assuming it can be in slope-intercept form):

`y = (1)/(2)x-2`

Explanation:

When knowing the slope of a line and its y-intercept, you can write the line's equation in slope-intercept form, or y = mx + b format. To write a full equation, substitute the m and the b for real values.

The m represents the slope of the line. Thus, substitute
`(1)/(2)` for m. The b represents the y-intercept. Thus, substitute -2 for b. This gives us the following equation and answer:

`y = (1)/(2)x -2`
