Question

write an equation in slope-intercept form of the line that passes through the given point (-1, 2) and (0,0

Answer 1

y = -2x

Explanation:

The correct line equation is in the format:

y = mx + b

Where m is the slope and b is the y-intercept.

The formula for calculating the slope is:

`(y2 - y1)/(x2 - x1)`

Where (x1, y1) is the first set of coordinates and (x2, y2) is the second set.

Plug the values in:

`(0 - 2)/(0 - (-1))`

`(0 - 2)/(0 + 1)`

`(-2)/(1)`

= -2

So the format is now:

`y = -2x + b`

Plug the second coordinate set:

`2 = -2(-1) + b\\2 = 2 + b\\2 - 2 = b\\0 = b\\\\`

Meaning the equation in slope-intercept form is simply:

y = -2x

Hope this helps!

Answer 2

Y = -2x hope that’s right
