Question

What is the equation of a line that passes through points (0, 4) and (-4, -8)?

y = 2x + 4
y = 2x - 4
y = 3x + 4
y = 3x - 4

Answer 1

first find the slope \[\huge\rm m=\frac{ y_2-y_1 }{ x_2-x_1}\]
substitute x's and y's by their value

Answer 2

\[\large\rm (x_1 ,y_1)(x_2,y_2)=(0,4)(-4,-8)\] x's and y's

Answer 3

y=2x-4

Answer 4

how did you get that ?

Answer 5

idk how to do it

Answer 6

now substitute x's and y's by their values
remember first number in order represent x-coordinate
so find sole fist \[\huge\rm m=\frac{ y_2-y_1 }{ x_2-x_1}\]
substitute x's and y's by their value
