Question

Complete the equation of the line through (-6,-5) and (-4,-4).

Use exact numbers
y =
​

Answer 1

y=1/2x-2

Explanation:

You have to find the slope first. Which is 1/2

After that, you plug in the points to the equation. In other words, y=x+b, but in this case we already found X.

Then, you get your result which is -2.

And you put it all together.

Answer 2

`y = 2x + 8`

Explanation:

`( - 6 - ( - 4))/( - 5 - ( - 4)) = ( - 2 )/( - 1) = 2 \\ gradient = 2 \\ \\ y = mx + c \\ y = 2 * - 6 + c \\ - 4 = - 12 + c \\ - 4 + 12 = c \\ 8 = c \\ \\ \\ y = mx + c \\ y = 2x + 8`
