Question

There is a single point which is a solution to the linear equation y-3=1/2(x+4) that is obvious because the equation is in point slope form. There are an infinite number of points that are not so obvious. Find the coordinates of the obvious point, and then find two additional points.

Answer 1

y−3=
1
2
(x+4)
y=0.5x+5

Answer 2

@mathwiz916 wait, what??

Answer 3

im back

Answer 4

so..?

Answer 5

@mathwiz916 I'm confused on your response.

Answer 6

oh ok

Answer 7

@mathwiz916 could you help me more? what are the points?

Answer 8

google this y=0.5x+5

Answer 9

it will show u the graph

Answer 10

@mathwiz916 okay i did that.. but what does that have to do with what i'm asking??

Answer 11

the points are -10 and 5

Answer 12

So I would put (-10,5) and (4,-3) ? @mathwiz916 I need 2. Sorry if I sound stupid lol.

Answer 13

here idk how to realy like explain so @welshfella can u help her out?

Answer 14

@mathwiz916 sorry ;/ and thank you.

Answer 15

lol dont be sorry its my fault

Answer 16

its a funny question
i would say that the point (-4,3) is the most obvious :- x = 4 when y = 3
because -4 makes the right side zero and 3 makes left side 0

3 - 3 = 0.5(-4+4)
0 = 0

Answer 17

you can find 2 more points by putting x = 0 and finding y , and vice versa

Answer 18

* typo x = -4 when y = 3

Answer 19

@welshfella math is my worst enemy right now.. I got (-4,3) but I don't get how to get 2 additional points..

Answer 20

y - 3 = 0.5(x + 4)
let x = 0
y - 3 = 0.5(0 + 4)
y - 3 = 0.5*4
y - 3 = 2

so what is y ?

Answer 21

and to get another point plug in y = 0 into the equation and solve for x

Answer 22

y - 3 = 2
add 3 to both sieds

y - 3 +3 = 2 + 3
y = 5

so another point is (0,5)

Answer 23

when y = 0
0 - 3 = 0.5(x + 4)
-3 = 0.5x + 2

solve for x

Answer 24

gotta go right now

Answer 25

@welshfella omg! Thank you so much for your help!
