The graph of a line passes through the points (0, -2) and (6.0). What is

9966 [12]

Answer:

$y=\frac{1}{3}x-2$

Step-by-step explanation:

The equation of a line is given in the form $y=mx+b$

Where

m is the slope with formula $m=\frac{y_2-y_1}{x_2-x_1}$

and

b is the y-intercept [y axis cutting point of line]

Given the two points (0, -2) and (6,0),

x_1 = 0

y_1 = -2

x_2 = 6

y_2 = 0

Now, we find m using formula:

$m=\frac{0+2}{6-0}=\frac{1}{3}$

Now we have

$y=\frac{1}{3}x+b$

Finding b, we plug in any (x,y) point. Lets put (6,0) and find b:

$y=\frac{1}{3}x+b\\0=\frac{1}{3}(6)+b\\0=2+b\\b=-2$

Thus,

equation of line = $y=\frac{1}{3}x-2$

ABC is a dilation image of DEF. What is the scale factor?

GrogVix [38]

The complete question in the attached figure

we know that
length side AB=8 units
length side DE=4 units

[ABC]=[DEF]*[scale factor]
then
[scale factor ]=[ABC]/[DEF]---------> 8/4--------> 2

the answer is
the scale factor for a dilation image of DEF to obtain ABC is 2

Can someone check my math homework? Please I need it to be checked.

dmitriy555 [2]

I have to say this is wrong because you subtracted 3 and 3 is the variable term. So what you need to do is to add 9 to both side to get 3x by it self. Then divide by 3 and then x=6
