write the equation of the line perpendicular to y= 5/2x+3 that passes through the point (-7,9). Type an answer using slope-inter
omeli [17]

Answer:

 5y = -2x + 31

Step-by-step explanation:

Given equation:

      y = \frac{5}{2} x + 3

Coordinate  = (-7,9)

Unknown:

Equation of the line perpendicular  = ?

Solution:

The slope - intercept format of a line is given as;

      y = mx + c

where y and x are the coordinates

           m is the slope

           c is the y-intercept

y = \frac{5}{2} x + 3

 From the given equation; slope is \frac{5}{2}

       

A line perpendicular will have a slope that is negative and the inverse of this;

      slope of perpendicular line  = -\frac{2}{5}

Since y= 9 and x = -7;

  So;

            9 = \frac{-2}{5}  x (-7) + C

            9 = \frac{14}{5} + C

           C  = 9 - \frac{14}{5}   = \frac{31}{5}

Now,

       y  =  -\frac{2}{5}x +  \frac{31}{5}

mulitply through by 5;

     5y = -2x + 31

Help what do I do do i just write y-3x+5 or solve it ​
Rina8888 [55]

Answer:

y=-3x+5

Step-by-step explanation: Yes you have it correct. The question is asking for you to put it into an equation that fits the slope and y-intercept which is slope-intercept form. Additional note, when you have a problem like this and it doesn't say what type of equation form to put it in, put it in slope-intercept form for simplicity's sake.

Which statement is true about this equation? 3(-y 7) = 3(y 5) 6.
Ahat [919]

The statement that is true about the equation 3(-y + 7) = 3(y + 5) + 6 is;

Statement A; The equation has one solution, y = 0

The given equation is;

3(-y + 7) = 3(y + 5) + 6

Expanding the brackets gives us;

-3y + 21 = 3y + 15 + 6

-3y + 21 = 3y + 21

Using subtraction property of equality, subtract 21 from both sides to give;

-3y = 3y

Using addition property of equality, add 3y to both sides to give;

-3y + 3y = 3y + 3y

6y = 0

Using division property of equality, divide both sides by 6 to get;

y = 0

The missing statements are;

A. The equation has one solution, y = 0.

B. The equation has one solution, y = -1.

C. The equation has no solution.

D. The equation has infinitely many solutions.
