Linear equation: d = m t + b
If the graph of the position of the second object is parallel to d = 2.5 t +2.2, than m = 2.5
t = 0, d = 1
1 = 2.5 · 0 + b
b = 1
Answer: A ) d = 2.5 t + 1
Answer:
to be parallel
slope should be equal
for first question
y=1/3X +2
comparing with y=m1x+c
slope = 1/3
similarly for second equation
y=1/3x -4
comparing with y=m2x + c
m2= 1/3
since m1=m2
lines are parallel
Answer: x = 7
Step-by-step explanation:
-5x + 3(x + 5) = 1
-5x + 3x + 15 = 1
-2x + 15 = 1
-2x = -14
x = 
x = 7
Slope of a line is represented by the formula:
M = y2 - y1 / x2 - x1
Substitute the coordinates in.
M = 1 - (-5) / 4 - 2
M = 1 + 5 / 4 - 2
M = 6 / 2
M = 3
The slope of a line passing through the points (2, -5) and (4, 1) is 3.
Solution: C) 3
