5 0

Step-by-step explanation:

Paralle lines have the same slope.

The slope-intercept form of an equation of a line:

y=mx+b

m - slope

b - y-intercept

We have

5y+9=-2x

Convert to the slope-intercept form:

5y+9=-2x           <em>subtract 9 from both sides</em>

5y=-2x-9         <em>divide both sides by 5</em>

y=-\dfrac{2}{5}x-\dfrac{9}{5}\to m=-\dfrac{2}{5}

Each of the answers to choose from is not the line equation sought.

The equation:

y=-\dfrac{2}{5}x+b where <em>b</em> is any real number.

Guys i need your HELP ASAP​

To solve this, you’ll first need to solve for their slopes.

The slope for line Q is y2-y1/x2-x1 = -8-(-2)/-8-(-10) = -3

We know that the lines are perpendicular so the negative reciprocal of -3 is 1/3

The equation you get it y = 1/3x + b.

Now you will need to solve for b by substituting in the first ordered pair of line R.

2 = 1/3(1) + b.

Once you solve for b, you should get 5/3 and y = 1/3x + 5/3

Now, to find a, you will need to substitute in 10 from the second ordered pair into x in your new equation.

y = 1/3(10) + 5/3.

Your solution should be 5.

So your answer is: a = 5

HELLLLLLP!!!!! PLEASE!!!!
blagie [28]

Answer: Slope: -1    Y-intercept: -4

Step-by-step explanation:

Slope formula:

m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }

m=\frac{-13 -(-6)}{9-2}= m=\frac{-13 + 6}{9-2}  

m=\frac{-7}{7\\}

m = -1

When you draw this on the graph, the y-intercept is -4.

y = -4
