Write an equation of each line in slope-intercept form
1) Y=-6x-3
2) Y=-2x-6
3) Y=-3x-6
4) Y=2x-3

y= -2x -6

Step-by-step explanation:

the first thing is now we have 2 points which it ( -3 , -1 ) & (0 , -6 ) so we can use the formula of gradient to find the line's gradient.

formula of gradient : y2 - y1 / x2 - x1

after we find out the gradient of the line which is -2 and we can choose a point which is (-3,-0)/(0,-6) to sub into y = mx + c :

m = -2 , a point ( -3 , 0)

0 = -2 (-3) + c

0 = 6 + c

-6 = c

c = -6

now we rewrite it again the make the equation become complete : y = -2x - 6
