Question

Find three solutions of the equation y=7x-5. (A)(3,-26),(-1,-12),(3,16) (B)(-3,-26),(-12,-1),(16,3) (C)(-3,-26),(3,16),(1,-12) (D)(-3,-26),(-1,-12),(3,16)

Answer 1

(D)(-3,-26),(-1,-12),(3,16)

Explanation:

Given : y=7x-5.

To find : Find three solutions of the equation .

Solution : We have given that y=7x-5.

We need to choose the values from the given option

Let x = -3

y = 7(-3) -5

y = -21-5

y = -26

(-3,-26)

For second solution

Plug x = 3

y = 7( 3) -5

y = 21 -5

y = 16

Then ( 3, 16)

Now , plug x = -1

y = 7(-1) -5

y = -7-5

y = -12

( -1,-12)

Therefore, (D)(-3,-26),(-1,-12),(3,16)
