What the equation parallel to y=-1/5x +7 and containing the point(-10,-3)
Agata [3.3K]

The equation of line parallel toy=-\frac{1}{5} x +7 and containing the point(-10,-3) is y=-\frac{1}{5}x-5

Step-by-step explanation:

We need to write the equation parallel to y=-\frac{1}{5} x +7 and containing the point(-10,-3)

The standard form of point slope equation is:

y=mx+b

where m is slope and b is y-intercept

Comparing the given equation  y=-\frac{1}{5} x +7 with standard form the slope is m= -1/5

Since the lines are parallel the slope of new line is m = -1/5

Now finding b (y-intercept)

Using slope m=-1/5 and point (-10,-3)

y=mx+b\\-3=-\frac{1}{5}(-10)+b\\-3=2+b\\b=-3-2\\b=-5

So, b= -5 and slope = -1/5 the equation of new line is:

y = mx+b\\y=-\frac{1}{5}x-5

So, The equation of line parallel toy=-\frac{1}{5} x +7 and containing the point(-10,-3) is y=-\frac{1}{5}x-5

Find X AND Y! pleas help me! only reply if you KNOW IT thank you
lawyer [7]

The measures of the legs of the right triangle are:

X = 2.5

Y = 4.3

<h3>How to find the values of x and y?</h3>

In the image, we can see a right triangle with a hypotenuse with a value of 5, and a known angle.

To find the values of X and Y (the legs of the triangle) we can use the two relations:

Sin(a) = (opposite cathetus)/(hypotenuse)

Cos(a) = (adjacent cathetus)/(hypotenuse)

In this case, we have:

a = 30°

hypotenuse  = 5

opposite cathetus = X

adjacent cathetus = Y.

Replacing that in the relations we get:

Sin(30°) = X/5

Sin(30°)*5 = X = 2.5

cos(30°) = Y/5

cos(30°)*5 = Y = 4.3
