Question

Some help me please, will medal and fan?!
What is the equation of a line that passes through (4, 7) and has a slope of −14?

Answer 1

\[\frac{ y - y _{1} }{ x - x _{1} } = m\]

Answer 2

A)\[y=\frac{ x }{ 4 }-\frac{ 7 }{ 4 }\]
B) \[y=-\frac{ x }{ 4 }+\frac{ 7 }{ 4 }\]
C) \[y=-\frac{ x }{ 4 }+8\]
D) \[y=\frac{ x }{ 4 }+8\]

Answer 3

what is the slope? (-4)

Answer 4

the equation is y =m(x)+c put in slope m,and x given =4 and y given =7 and find c

Answer 5

I got \[C=-\frac{ 7 }{ 16 }\] @jamaica25 @rishavraj

Answer 6

@itsdaniela whts the slope ???? is it -4
????

Answer 7

yes thats what i used @rishavraj

Answer 8

then
7 = 4 (-4) + C
7 = -16 + C
C = 23

Answer 9

According to ur question

Answer 10

So which one is right? @rishavraj

Answer 11

i m confused ....r u sure tht the question or its options r correctly mentioned?????

Answer 12

it looks like the given slope is -1/4 Not -14

Answer 13

@phi awesome...:)))
its really supposed to be \[-\frac{ 1 }{ 4 }\]
@itsdaniela use slope = -1/4 ..and solve it..

Answer 14

Using the same equation? @rishavraj

Answer 15

yup u can use any one of the two
\[\frac{ y -y_1 }{ x - x_1 } = m\]
or
y = mx + c

Answer 16

Thank you soo much! @rishavraj

Answer 17

u r most welcome,....:)
