Write the equation of the line, in slope-intercept form, that passes through the point (-2, 3) and has slope 3.

a. y = -3x + 9
b. y = 3x -9
c. y = -3x -9
d. y = 3x + 9

➷  Substitute the values into y = mx + c

3 = 3(-2) + c

3 = -6 + c

+ 6 to both sides

9 = c

Thus, your answer is D. y = 3x + 9

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^

D. y = 3x + 9 is your answer.

Step-by-step explanation:

What you do is use the slope-intercept formula:

y - y_1 = x (x - x_1)

3 is y and -2 is x.

y - 3 = 3 (x + 2)

y - 3 = 3x + 6

y = 3x + 9

D. y = 3x + 9 is your answer.

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .
