Question

What is the slope-intercept form of the function that contains the point (–3, 2) and has a slope of –2?

y = __ x + __

Answer 1

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

Answer 2

Not really

Answer 3

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.

Answer 4

Can you try now ?

Answer 5

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

Answer 6

yes...

Answer 7

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

Answer 8

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

Answer 9

@xavier123

Answer 10

y = -2x+c

for (-3,2)

2 = -2(-3)+c => 2 = 6 + c

=> c = -4

hence, y= -2x-4

Answer 11

oh okay... Thank you!

Answer 12

most welcome :)
