Consider the given equation is
and one of the 6 in the options is -6.
Given:
The equation is

To find:
The value of x.
Solution:
We have,

Subtracting 3 from both sides, we get


Divide both sides by -2.


Therefore, the value of x is -6.
D. 21cm because you divide all sides by 2 then get your slope form and multiply by seven
The equation of the line is y = 0.8x - 1.4 if the slope of the line is 0.8 and line passes through coordinates (-2,-3)
<h3>What is a straight line?</h3>
A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:

The slope m = 0.8
The line passing through coordinates (-2,-3)
y = mx + c
y = 0.8x + c
Plug the point in the equation.
-3 = 0.8(-2) + c
c = -1.4
y = 0.8x - 1.4
Thus, the equation of the line is y = 0.8x - 1.4 if the slope of the line is 0.8 and line passes through coordinates (-2,-3)
