Answer:
8/25, 3/6, 3/5, 0.89 is from least to greatest
Calculate the slope using the slope formula
m = (y2-y1)/(x2-x1)
m = (5-(-1))/(-6-(-8))
m = (5+1)/(-6+8)
m = 6/2
m = 3
The slope is 3
The point your teacher uses is (-6,5) because of the y-5. Note how it's in the form y-y1 where y1 = 5
So (x1,y1) = (-6,5)
Point Slope Form
y-y1 = m(x-x1)
y-5 = 3(x-(-6))
y-5 = 3(x+6)
The equation in point slope form is
y-5 = 3(x+6)
So you'll type 3(x+6) into the box
Answer:
Step-by-step explanation:
Equation of circle is
Where (a, b) is center of circle and r is radius
Here (a, b) = (6, -3) and radius can be determined by calculating the distance from center to point (1, 1)
Substituting values in equation of circle
