Write the equation of a line in slope intercept form given;<br> (6,-3), (0, 5)
olganol [36]

Answer:

y=(-4/3)x+5

Step-by-step explanation:

so you want to start by using y=mx+b

step one: find the slope (remember m is the slope in this)

m= \frac{y2-y1}{x2-x1}

m= \frac{5+3}{0-6}

m= \frac{8}{-6}

m= - \frac{4}{3\\}

step two: insert the value we found for m into the equation and take one of the given points and insert the x and y into the equation (im using (0,5)) and solve for b.

y=mx+b

5= -4/3(0)+b

5=b

step three: rewrite y=mx+b with the values we found for m and for b

y=(-4/3)x+5

7) What is the equation of a circle with the center (-8, 9) and the radius of 10?​
lutik1710 [3]

Answer:

<h3>(x+8)² + (y - 9)² = 100</h3>

Step-by-step explanation:​

The general equation of a circle is expressed as;

(x-a)² + (y - b)² = r² where;

(a, b) is the centre of the circle

r is the radius

Given

Centre (-8, 9) where a = -8, b = 9

radius r = 10

Substitute into the formula to get the required equation;

(x-(-8))² + (y - 9)² = 10²

(x+8))² + (y - 9)² = 10²

(x+8)² + (y - 9)² = 100

Hence the required equation is (x+8)² + (y - 9)² = 100
