Answer 3

Oops..!! you just missed the shot.. :(

Answer 4

Equation of line with one point and slope is given as:

\[y -y_1 = m(x-x_1)\]

Answer 5

d would be right if it would have been : \(y - 46 = 3(x-12)\).. :)

Answer 6

Any more try you wanna do?

Answer 7

Slope is \(3\), that is right, so select equation with slope = 3 first.. :)

Answer 8

so its b?

Answer 9

Yep.

Answer 10

ok hang on and thank you let me get another

Answer 11

Point is \((6, 28)\) and \(m=3\), so:

\(y - 28 = 3(x-6)\)

Answer 12

Post it here only.. :

Answer 13

Which ordered pairs in the form (x, y) are solutions to the equation

7x – 5y = 28?



Choose all answers that are correct.



A.


(−6, −14)


B.


(−1, −7)


C.


(4, 10)


D.


(7, 9)


i believe a,c,and d

Answer 14

I am not seeing it, I am seeing boxes there.. :) Post it again and nicely.. :)

Answer 15

What is the sign between 7x and 5y ?? Is it plus or minus??

Secondly, write A and B options again,,,

Answer 16

\(a\) is right.. Why you chose \(c\) and \(d\) ?

Answer 17

Just put that values in place of x and y, and check whether you are getting 28 or not.. :)

Answer 18

Like for \(a\), (-6,-14)

\[7(-6) -5(-14) = -42 + 70 = 28\]

yes you are getting \(28\) here, so this is right.. Likewise do for others and check.. :)
