Answer:

3 x - y = 6

Explanation:

the equation of a line is

ax + by = c

express the slope initially in the form of y=mx+b

b is the y- intercept (the point where it crosses the y axis)

m is basically the slope, to find m, you have to use a specific formula...

m = (y2 – y1) / (x2 – x1)

(x1, y1) (x2, y2) are 2 coordinate points...

(3,3) and (1, -3)

m = -3 -3 divided by 1 - 3 = -6/-2 = 3

so your formula for now is .. y = 3x + b (you dont know what b is yet)

Now, substitute the points into the equation.

3 = 9 + b. b = -6

final formula is,

Y=3x -6

u can also rearrange the formula in a standard form:

3x - y = 6

I REALLY HOPE THIS HELPS U!!
