Answer:

(-7, 31)

Step-by-step explanation:

To solve this equation, simply plug in the numbers. For example, with -3 and -11, you simply plug them into the equation:

-11 = -5 (-3) - 4
After you solve this, you'll see the equation does not come out to -11; rather, it comes out to +11.

Repeat this with all equations, and you will see which are correct. Be careful, however, and remember which number goes into which value.

Write an equation for the perpendicular line to the line whose equation is 4y-5x=20 that contains the point (-2,-3)

yuradex [85]

Answer:

4x + 5y = - 23

Step-by-step explanation:

the equation of a line in slope-intercept form is

y = mx + c ( m is the slope and c the y-intercept )

rearrange 4y - 5x = 20 into this form

add 5x to both sides

4y = 5x + 20 ( divide all terms by 4 )

y = $\frac{5}{4}$ x + 5 ← in slope-intercept form

with slope m = $\frac{5}{4}$

given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ , hence

$m_{perpendicular}$ = - 1 / $\frac{5}{4}$ = - $\frac{4}{5}$

y = - $\frac{4}{5}$ x + c ← is the partial equation

to find c substitute (- 2, - 3) into the partial equation

- 3 = $\frac{8}{5}$ + c ⇒ c = - $\frac{23}{5}$

y = - $\frac{4}{5}$ x - $\frac{23}{5}$ ← in slope-intercept form

multiply all terms by 5

5y = - 4x - 23 ( add 4x to both sides )

4x + 5y = - 23 ← in standard form
