Question

Giving medal for the answer, plz help ! not good at this


Write a rule for the linear function whose graph has slope m and contains the given point.


m = 3; (-2, -2)



a.

y = 3x + 4

c.

y = 3x + 2


b.

y = 3x - 4

d.

y = 3x - 2

Answer 1

The slope-intercept form of the equation of a line is
\(y = mx + b\)
where m = the slope, and
b = the y-intercpet.

Answer 2

y-y1=m(x-x1)

x1=-2 and y1=-2

y+2=3(x+2)

y+2=3x+6

y=3x+6-2

y=3x+4

Answer 3

Start writing your equation in that form using the info you have, m = 3:
\(y = 3x + b\)
To find b, insert the point you are given, (-2, -2), into x and y, and solve for b.

Answer 4

thanks for the help!

Answer 5

Anytime.

Answer 6

\( -2 = 3(-2) + b \)

\(-2 = -6 + b\)

\(4 = b\)

So you get:

\(y = 3x + 4\)
