Convert 7x + 3y = −1 to slope-intercept form.
maksim [4K]
Hi there!

Let's solve this problem step by step!

7x + 3y =  - 1
To convert this formula to slope-intercept form, we must isolate y.

First bring 7x to the left by subtracting 7x from both sides of the equation.
3y =  - 7x - 1

Finally we need to divide both sides of the equation by 3.
\frac{3y}{3}  =  \frac{ - 7x - 1}{3}

Do some simple algebra and we find:
y =  -  \frac{7}{3} x -  \frac{1}{3}   \\ y =  - 2 \frac{1}{3} x -  \frac{1}{3}
~ Hope this helps you!

The diameter of Circle Q terminates on the circumference of the circle at (3,0) and (-4,0). Write the equation of the circle in
sladkih [1.3K]

Answer: (x+0.5)^2+y^2=49

Step-by-step explanation:

Given

The diameter of circle terminates on the circumference with coordinates

(3,0) and (-4,0)

Distance between the two points is the diameter of the circle. The distance is given by distance formula i.e. d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}

Insert the values

\Rightarrow d=\sqrt{\left(-4-3\right)^2+\left(0-0\right)^2}\\\\\Rightarrow d=\sqrt{(-7)^2+0}\\\Rightarrow d=7\\\text{So, the radius is r=}3.5\ \text{units}

The center of the circle is the mid-point of the two points i.e.

\Rightarrow x=\dfrac{3-4}{2}\\\\\Rightarrow x=-\dfrac{1}{2}\\\\\Rightarrow y=\dfrac{0+0}{2}\\\\\Rightarrow y=0\\\Rightarrow (x,y)\rightarrow (-\dfrac{1}{2},0)

The equation of the circle is given by

\Rightarrow (x-(0.5))^2+(y-0)^2=7^2\\\\\Rightarrow (x+0.5)^2+y^2=49
