A line has this equation: x + y = 6

Mathematics

Answer:

the equation of the line will be: y=x-4

Step-by-step explanation:

Equation of line: x + y = 6

We need to write an equation for the perpendicular line that goes through

(5, 1).

The equation will be in slope-intercept form y=mx+b where m is slope and b is y-intercept

Finding Slope:

Equation of line given is: x+y=6

Writing it in slope-intercept form: y=-x+6

The slope of this line is m = -1 (By comparing it with y=mx+b we get m = -1)

Since the required line is perpendicular, their slopes will be opposite inverse of each other i.e. m_1=-\frac{1}{m_1}

So, slope of required line will be: m=1

Now, using the point (5,1) and slope m=1 we can find y-intercept

y=mx+b\\1=1(5)+b\\1=5+b\\b=1-5\\b=-4

So, we get y-intercept b = -4

Now, the equation of required line, having slope m=1 and y-intercept b = -4

y=mx+b\\y=1x-4

So, the equation of the line will be: y=x-4

Find the center and radius of the circle with the equation (x+5)^2+(y-2)^2=25
chubhunter [2.5K]

Answer:The center is (-5,2)

The radius is 5

Step-by-step explanation:

Equation of a circle is:

(x-h)^2+(y-k)^2=r^2

(x+5)^2+(y-2)^2=5^2

Comparing both equations we get :

The center (-5,2)

The radius is 5

Calculate the value of k=xy
Masteriza [31]

Answer:

Since k is constant, we can find k given any point by multiplying the x-coordinate by the y-coordinate. For example, if y varies inversely as x, and x = 5 when y = 2, then the constant of variation is k = xy = 5(2) = 10. Thus, the equation describing this inverse variation is xy = 10 or y = .planation:

Someone please show me how to do this
Degger [83]
The 1 represents the y intercept so a point is (0,1). To find other points, plug in values for x. For example, plus in x and you get a y value of 2. So just plot a number of points and then connect them with a curved line( called a parabola).
