What is the solution to the system of equations below? y = one-half x minus 4 and y = negative 2 x minus 9 (–2, –5) (–2, –3) (2,
Maurinko [17]

We have been given a system of equations y=\frac{1}{2}x-4 and y=-2x-9. We are asked to find the solution of our given system of equations.

To solve our system of equations, we will equate both equations as:

\frac{1}{2}x-4=-2x-9

\frac{1}{2}x-4+4=-2x-9+4

\frac{1}{2}x=-2x-5

\frac{1}{2}x+2x=-2x+2x-5

\frac{1}{2}x+\frac{4}{2}x=-5

\frac{1+4}{2}x=-5

\frac{5}{2}x=-5

\frac{2}{5}\cdot \frac{5}{2}x=-5\cdot \frac{2}{5}

x=-2

Upon substituting x=-2 in equation y=-2x-9, we will get:

y=-2(-2)-9

y=4-9

y=-5

Therefore, the solution of our given system of equations would be (-2,-5) and option A is the correct choice.

Write an equation of a line in slope-intercept form with the given slope and y-intercept.
Nostrana [21]

Answer:

<em>y</em> = -6<em>x - </em>2

<em>y </em>= <em>x</em> - 12

Step-by-step explanation:

Slope-intercept equation for line of slope <em>m</em> and <em>y</em>-intercept <em>b</em>:

<em>y</em> = <em>mx </em>+ <em>b</em>

A. <em>m</em> = -6, <em>b</em> = -2

<em>y</em> = -6<em>x - </em>2

B. <em>m</em> = 1, <em>b </em>= -12

<em>y </em>= <em>x</em> - 12
