Answer:
Step-by-step explanation:
Slope= -5
y-intercept= 4
y intercept : (0,6)
Explanation:
Use the formula:
. y = mx + b
Find m (the slope), using 2 random points of the graph: (-2,0) and (1,9)
. m = (y-y1) / (x-x1)
m = (0-9) / (-2-1)
m = -9 / -3
m = 3
Replace m in the equation:
. y = 3x + b
Find b by replacing y and x by a random point of the graph: (1,9)
. 9 = 3*1 + b
b = 9 - 3
b = 6
Replace b in the equation:
. y = 3x +6
To find the y-intercept replace x by 0 in the equation:
. y = 3*0 +6
y = 0+6
y = 6
=> y-intercept : (0,6)
Answer:
x = 2
Step-by-step explanation:
A circle is always similar to another circle, because we can always map one onto the other using only dilations and rigid transformations.
Step-by-step explanation:
Two Circles are said to be similar if all the linear measurements of the circles are proportional.
Lets consider if two circles have a certain ratio of their radii, , it definitely mean that all the other corresponding ratios will also have that same ratio.
<u>Concentric circles are defined as the circles which have a common center. The area between the two concentric circles having difference in their radii is Known as annulus.</u>
<u></u>
The most important property of a circle is that all points on the circle are equidistant (i.e. having the same distance) from the center point.
<u>A circle is always similar to another circle, because we can always map one onto the other using only dilations and rigid transformations.</u>
