Question

Write an equation in slope-intercept form for the line that satisfies the following condition. The line passes through (25, 3), and is parallel to the graph of y =9/4x + 5. If a decimal, round to the nearest whole number

Answer 1

i need ans

Answer 2

i aint got noone to help me with this no teacher just computer stuff

Answer 3

?????

Answer 4

y = mx + c is the slope intercept form

Answer 5

parallel to the graph of y =9/4x + 5, so has the same gradient (m) value

Answer 6

and use one of the points it passes through to find the y intercept (c)

Answer 7

i need answer

Answer 8

so work it out
do the math yourself and i'll help you, but i'm not an answer generator dude

Answer 9

would you like more clarification on any of the points...?

Answer 10

na im good

Answer 11

@Jack1 can you help me on this problem as well,

Answer 12

slope intercept i though it was y=mx+B

Answer 13

no worries
the final equation should be in the slope intercept form, so
y = mx + c
or
y = mx + b if that's the way you were taught, either works

now we need to work out "m" and "b"

so...

Answer 14

m is the gradient
so if a line is parallel to our line, then it must have the same gradient
so we have a parallel line:
\[y =(\frac{ 9 }{ 4 }) x + 5\]

so first step, steal the gradient from there

now all we have left is the B value ( y intercept)

Answer 15

to find that, we need a point along our line
we're given the point (25, 3)

hang on... are you guys following ok...?

Answer 16

yes

Answer 17

cool, so what's your equation so far?
y = mx + B
so your value for m is...?@amandasoto144

Answer 18

25?

Answer 19

no... 9/4, same as the other given equation

Answer 20

oh i didnt see that part till now sorry

Answer 21

so b is 5?

Answer 22

all good
ok, so we have the point (25, 3) somewhere on our line (which is an x, y point)
and we have the gradient
so if
y = mx + B
we can use
3 = 9/4 * 25 + B to find b

Answer 23

no, only the gradients are the same in parallel lines, not the y intercepts (b values)

Answer 24

so 3 = 56.25 + b

therefore b = ...?

Answer 25

im sorry im confused, so i know how you got 56.25 but am i suppose to add 5 or 3?? how am i suppose to find B?? or is 56.25 B??

Answer 26

is the answer 59.25??

Answer 27

no, we dont know B yet, so we need to isolate it in the equation
y = mx + b
3 = 56.25 + b ( so take 56.25 from both sides)
3 - 56.25 = 56.25 + b - 56.25
-53.25 = b

Answer 28

so your final equation is
y = m x + c
just sub in the values of m and b you worked out

Answer 29

* b or * c... whatever you want to call it, sorry

Answer 30

so Y=9/4x+53.25

Answer 31

?

Answer 32

almost, negative value for b remember

Answer 33

-53.25

Answer 34

but you said plug it in from both sides, and i saw two negatives so i thought it was positive, my fault sorry

Answer 35

so Y=9/4x-53.25

Answer 36

perfect

Answer 37

oh wow, thank you!

Answer 38
