Question

Please solve the question below!

Write the equation of a line in slope-intercept form that crosses through the points (-3, -7) and (12, 3)

Answer 1

Explanation:

Hey there!

The points through which the line passed are; (-3,-7) and (12,3).

Note: Use double point formula.

`(y - y1) = (y2 - y1)/(x2 - x1) (x - x1)`

Keep all values.

`(y + 7) = (3 + 7)/(12 + 3) (x + 3)`

Simplify it.

`(y</u><u> + 7) = (10)/(15) (x + 3)`

`(y + 7) = (2)/(3) (x + 3)`

`y + 7 = (2)/(3) x + 3 * (2)/(3)`

`y = (2)/(3) x + 2 - 7`

`y = (2)/(3) x - 5`

Therefore, the required equation is; y = 2/3x - 5.

Hope it helps...
