(b) Write the equation for Sidewalk 2 in point-slope form and then in slope-intercept form.
(c) Is the system of equations consistent independent, coincident, or inconsistent? Explain.
(d) If the two sidewalks intersect, what are the coordinates of the point of intersection? Use the substitution m

Answer 1

Are you there?

Answer 2

yes

Answer 3

answer the question its your medal

Answer 4

What seems to be the problem? Where you got stucked?

Answer 5

i dont understand the question nor how to do it can you answer the question

Answer 6

Can you rewrite the 'x' and 'y's, I'm pretty sure it's a table.

Answer 7

i can't that's how the question is

Answer 8

I don't understand this:
Sidewalk 1
x
y
2
7
0

Answer 9

here i'll put a picture

Answer 10

So

Answer 11

The question asks you to find the equation of Sidewalk 1. To construct an equation you will need a coordinate and a slope. From the table you've got (2,7) and (0,3).
Find the slope by
\[m=\frac{y-y_1}{x-x_1}= \frac{7-3}{2-0}=\frac{4}{2}=2\]
Now you have the slope, simply pick a coordinate and substitute the slope and the coordiate into this
\[y-y_1=m(x-x_1)\]
\[y-3=2(x-0) \\ \\ y=2x+3\]

Answer 12

Now do question (b) using the same method

Answer 13

so for slope a it is y−3=2(x−0)y=2x+3 or just y=2x+3

Answer 14

What do you think? of course its y=2x+3

Answer 15

i have no common sense at math lol

Answer 16

Once you get it it's very very easy

Answer 17

can you answer part b im still unsure sorry for the inconvience

Answer 18

No you need to try it for yourself, just follow my steps and do it

Answer 19

ill try
