Answer:
(x+8)² + (y+13)² = 169
Step-by-step explanation:
Equation of circle:
(x-h)² + (y-k)² = r²
(h,k) is the centre, r is the radius
(x-(-8))² + (y-(-13))² = 13²
(x+8)² + (y+13)² = 169
Answer:
4 pens will cost $4.84
Step-by-step explanation:
1.21 times 4 = 4.84
The line's y-intercept is -3 as per the information given in the table.
<h3>What is meant by slope?</h3>
The slope or gradient of a line is a numerical representation of a line's steepness and direction in mathematics. The reason for this usage is unknown, but it first appears in English in O'Brien (1844), who wrote the equation for a straight line as y = mx + b, and in Todhunter (1888), who wrote it as y = mx + c. In this case, m stands for the line's slope.
Slope is the result of calculating the ratio of vertical change to horizontal change between (any) two distinct points on a line.
We know that,
y=m x +c
From the table the points are,
A(-2,5)
B(-1,1)
C(0,-3)
D(1,-7)
Substituting the C point in the above equation we get,
-3=m(0)+c
c=-3
Consequently, the line's y-intercept is -3.

Answer:
see below
Step-by-step explanation:
Subtract 62, then divide by -32 to put the equation into intercept form:
... x/(-6.4) + y/(-10 2/3) = 1
This tells you the x-intercept is -6.4, and the y-intercept is -10 2/3. A line through these two points is your graph.
