Explain the steps for writing an equation of a line that passes through (4,7) and has a slope of 1/2
Marat540 [252]

Answer:

The equation would be y = 1/2x + 5

Step-by-step explanation:

To find this equation, we start by using point slope form, and then plugging the slope in for m and the point in at (x1, y1).

y - y1 = m(x - x1)

y - 7 = 1/2(x - 4)

And now we solve for y.

y - 7 = 1/2(x - 4)

y - 7 = 1/2x - 2

y = 1/2x + 5

A circle is graphed on this coordinate plane. What is the radius in units of the circle and what is the equation of the circle?​
Anastasy [175]

Answer:

The radius is 4 units, and the equation of the circle is:

(x - 3)^2 + (y + 5)^2 = 16

Step-by-step explanation:

A circle centered at the point (a, b) and with a radius R, is written as:

(x - a)^2 + (y - b)^2 = R^2

In the image, we can see that a segment that cuts the circle in two halves is the segment between the points:

(-1, -5) and (7, - 5)

The distance between these points is the diameter of the circle.

Remember that the distance between two points (x₁, y₁) and (x₂, y₂) is:

D = √( (x₂ - x₁)^2 + (y₂ - y₁)^2)

Then in this case, the distance between the known points is:

D = √( (7 - (-1))^2 + (-5 - (-5))^2)

D = √( 8^2) = 8

The diameter of the circle is 8

Then the radius is:

R = 8/2 = 4

the radius is 4.

Now, to find the center of the circle we just need to go to any of the two extremes of the interval and count 4 units towards the center of the circle, this is:

(-1 + 4, -5) = (3, -5)

or

(7 - 4, -5) = (3, -5)

Then the center of the circle is the point (3, -5) and the radius is R = 4

The equation of the circle is:

(x - 3)^2 + (y - (-5))^2 = 4^2

(x - 3)^2 + (y + 5)^2 = 16

Find an equation of the line that passes through the point (3, 4) and is perpendicular to the line 2x - 5y = -3.
zzz [600]

\text{Hello there! :)}

\large\boxed{y = -\frac{5}{2}x + \frac{23}{2}}

\text{Begin by rewriting the given equation into slope-intercept form:}\\\\2x - 5y = -3\\\\-5y = -2x - 3\\\\y = \frac{2}{5}x + \frac{3}{5}\\\\\text{A perpendicular line has a slope of the opposite reciprocal, therefore:}\\\\\frac{2}{5} \text{ becomes } \frac{-5}{2}  \\\\\text{Substitute slope, y-coordinate and x-coordinate into slope-intercept formula:}\\\\4 = \frac{-5}{2}(3) + b\\ \\4 = -\frac{15}{2} + b\\\\\frac{8}{2} = -\frac{15}{2}+ b\\\\\frac{23}{2} = b\\\\

\\\text{Write the final equation:}\\\\y = -\frac{5}{2}x + \frac{23}{2}
