anonymous · Answer

do you know the slope intercept form of equation of a line ?

anonymous · Answer

Not really

anonymous · Answer

any straight line can be represented in the form of $$y = mx + c$$ where 'm' is called the slope of the line and 'c' is called the intercept.

anonymous · Answer

Can you try now ?

anonymous · Answer

would it be y=-2x+c to start with?

anonymous · Answer

yes...

anonymous · Answer

find the value of 'c' by substituting the point and you have your equation :)

anonymous · Answer

would it be y=-2x+2?? sorry i'm really bad at these :/

@xavier123

anonymous · Answer

y = -2x+c

for (-3,2)

2 = -2(-3)+c => 2 = 6 + c

=> c = -4

hence, y= -2x-4

most welcome :)
