The formula would be:
<span>y = mx + b
</span><span>
Now, let's look at the information we know. 
m = slope 
b = y-intercept
y-intercept = -6
x-intercept = -2
</span>
First, we would need to determine the slope. The formula for slope is m = \frac{ y_{2} - y_{1} } { x_{2} - x_{1} }

Plug your coordinates in and solve it. 
\frac{0 + 6}{-2 - 0} = 6/-2 = -3

Now, since we have the slope and y-intercept, we are ready to plug them into the formula. 
y = -3x - 6

I hope this helps!

You can easily find the slope of the line from these 2 intercepts / points.
                         0-[-6]
m = rise/run = ------------ = 6/2 = 3 = m
                          -2-0
Now stick values into the point-slope formula as follows:


                      y-(-6) = 3(x-0), or y + 6 = 3x, or y = 3x - 6 (answer)

line m passes through point (-2,-1) and is perpendicular to the graph of y=-2/3x+6. Line n is parallel to line m and passes thro
puteri [66]

Answer:

Hello...... here is a solution :

1 -  

Hello:

the   equation of "m" is : y = ax+b

the slope is a : a×(- 2/3) = -1......( perpendicular to a line : y=-2/3x+6 when the slope is -2/3 )

a = 3/2          

the line " n" that passes through (4, - 3) and  parallel to line "m" :  

when the slope is 3/2 ( same slope )

the equation in slope-intercept form of the line" n" is :

 y – (-3)= (3/2)(x – 4)

All you have to do is divide each one by its other number.  For example, 5.60 for 8 is the same as one for 0.70.  We accomplish this by dividing the 5.60 by 8.
So...
0.70
0.80
0.90
0.75
The first choice is the lowest.
