Write an equation that is parallel to the line 2x - 3y = 9 and passes through the point (4, -1).
insens350 [35]

Answer: y = \frac{2x}{3} - \frac{11}{3}

Step-by-step explanation:

Equation of the line given ;

2x - 3y = 9

To find the slope of the line we will make y the subject of formula , that is

3y = 2x - 9

y = \frac{2x}{3}-3

Therefore ; the slope = \frac{2}{3}

Two lines are said to be parallel if they have the same slope

This means that the slope of the second line = \frac{2}{3}

Using the formula y-y_{1}= m ( x - x_{1} ) to find the equation of the line , we have

y - (-1 ) = \frac{2}{3} (x - 4 )

y + 1 = \frac{2x}{3} -\frac{2}{3}(4)

y + 1 = \frac{2x}{3} - \frac{8}{3}

y = \frac{2x}{3}-  \frac{8}{3}  - 1

y = \frac{2x}{3} - \frac{11}{3}

Y=2x and -6x + 3y = 16 what are the x and y values?
Sedaia [141]

Answer:

NO SOLUTION

Step-by-step explanation:

Here  you're asked to solve a system of equations, linear equations in this case.

Since y = 2x, we can subst. 2x for y in the 2nd equation:

-6x + 3(2x) = 16

Combining the x terms results in 0 = 16, which is never true.  

Thus, this system of linear equations has NO SOLUTION.
