Please answer it correctly and I'll mark it​
kirza4 [7]

Answer:

Step-by-step explanation:

1) a very poor question indeed. It has at least two possible solutions

c = 3x + 2                                     or     c = 3(x + 2)

when x = 2

c = 3(2) + 2 = 8                           or      c = 3(2 + 2) = 12                  

when x = 5

c = 3(5) + 2 = 17                          or       c = 3(5 + 2) = 21

2)

y = x + 2

when x = 2

y = 2 + 2 = 4

when x = 5

y = 5 + 2 = 7

-4x+7y=-14 slope intercept form
fredd [130]

Answer:

The slope-intercept form of the given equation is,

y = \frac{4x}{7}-2

Step-by-step explanation:

The given equation of the line is,

- 4<em>x</em> + 7<em>y</em> = - 14

Adding '4<em>x</em>' on both sides of the above equation, we get

   - 4<em>x</em> + 7<em>y</em> + 4<em>x</em> = - 14 + 4<em>x</em>

⇒ 7<em>y</em> = 4<em>x</em> - 14

Now, dividing both sides of the above equation by '7', we get

       7<em>y</em> ÷ 7 = (4<em>x</em> - 14) ÷ 7

\implies y = \frac{4x}{7}-\frac{14}{7}

\implies y = \frac{4x}{7} - 2

This is the required equation of the line in slope-intercept form.
