Question

Write the equation of the line passing through the points (0, -4) and (-2, 2).

Answer 1

do you know a common linear equation formula?

Answer 2

u have 2 points ..can u calculate the slope ??

Answer 3

Answer 4

No, I do not, because my teacher has been on maternity leave and the substitute just kinda sits there not teaching but still giving the work that goes with the lessons.

Answer 5

I know a really easy way to find the slope that works :)

Answer 6

without an Equation.. Easier for me anyways

Answer 7

slope =(y2-y1)/(x2-x1)

Answer 8

take one point (x1,y1) and other as (x2,y2)

Answer 9

@*Shadow*
Oh?

Answer 10

will u try ??

Answer 11

Yes, but as I said I don't even know how or what to do and I am not familiar with any of this vocabulary due to poor education.

Answer 12

Ok, fukaawa.

Answer 13

My way is. find the difference between both (x) coordinates.

Answer 14

Answer 15

Math can be simple if the steps are broken down and you try your hardest. We understand that you are facing some limitation so try and follow along with the steps below.

Answer:

Linear formula: y=mx + b


m= slope =(change in y)/(change in x)
b= y- intercept

Step 1: calculate slope
m= slope =(change in y)/(change in x)= [2 - (-4)]/ [-2-0]=6/-2=-3

Step 2: calculate y-intercept by plugging in point values and slope value. ex (-2, 2)

y= mx + b
2 = -3 (-2) + b
2 =6 + b
2-6 = b
-4 =b

Step 3: rewrite equation with slope and y-intercept values

y= -3 x -4
