Solve the system of equations by elimination.

n200080 [17]

Answer:

Step-by-step explanation:

1. 2x - 9y = 23

2 x = 9 y + 23

y = (2 x)/9 - 23/9

2 x - 9 y - 23 = 0

2. 5x - 3y = -1

5 x + 1 = 3 y

y = (5 x)/3 + 1/3

5 x - 3 y + 1 = 0

I belive that should help you out a bit :D

Write an equation in point-slope form of a line that goes through the points (1,4) and (3,-10). Do not use any spaces in your an

olasank [31]

Answer:

y-4=-7(x-1) OR y-(-10)=-7(x-3)

Step-by-step explanation: The point-slope form is $y_$ - $y_{1}$ = $m_$ ( $x_$ - $x_{1}$ )

In slope-intercept form, the equation would be y = -7x + 11

You could find the slope by using the slope equation, $\frac{y_{2} -y_{1} }{x_{2} -x_{1} }$ .

Using that, you would get -7. Thus by inserting one of the points and the slope in the point-slope equation, you will get your answer.
