well, when x = 0, namely at the very beginning, y = 27, thus, that IS the initial value.
Answer:
m = -30
m = slope
Step-by-step explanation:
(1,57) and (2,27)
(x1,y1) and (x2,y2)
y2 - y1. 27 - 57
---------- =. ---------- =. -30/1 = -30
x2-x1. 2 - 1
Answer:
6√2
Step-by-step explanation:
from the graph the coordinates of the points are (2, 5) and (- 4, -1)
the distance is d= √(x2-x1)²+(y2-y1)² = √(-4-2)²+(-1-5)²=√72 = √2*2*2*3*3= 6√2
Answer:
Plan Two
Step-by-step explanation:
If you do all the math, which is not that hard, you can find the answer easily. I think if you tried to do it yourself, you would learn and benefit more.
First solve for the slope, m using the two points given. It doesn't matter which point you choose as point 1 or 2 as long as you're consistent.
m = (y2 - y1)/(x2 - x1)
point 1: (–6.4, –2.6)
point 2: (5.2, 9)
m = (9 - -2.6)/(5.2 - -6.4)
m = (9 + 2.6)/(5.2 + 6.4)
m = 11.6/11.6
m = 1
put the newly found slope into the linear equation for m
y = (1)x + b
y = x + b
Now solve for the y-intercept, b
by putting one of the given points
9 = 5.2 + b
b = 9 - 5.2
b = 3.8
final equation:
y = x + 3.8
