Answer:
Step-by-step explanation:
a). Point (x, y) from the graph represents,
x → Time in hours
y → Distance traveled by the bicyclist (in miles)
Therefore, point (4, 60) represents the distance 60 miles traveled by
the bicyclist in 4 hours.
b). Since, distance traveled (d) is proportional to the time taken(t).
d ∝ t
d = kt
k = 
Here k = constant of proportionality.
k =
= 15
c). Therefore, equation in the form of y = kx will be,
y = 15x
Answer:
(-1,4) is a solution to the system.
Step-by-step explanation:
For this problem, we can simply identify if this point is a solution by verifying the plugged in point values allow the left hand side to equal the right hand side.
(1) -2x - 3y = -10
-2(-1) - 3(4) ?= -10
2 - 12 ?= -10
-10 == -10
(2) -3x + y = 7
-3(-1) + (4) ?= 7
3 + 4 ?= 7
7 == 7
Since both equations are satisfied by this point, then we can say the point (-1,4) is a solution to the system. Additionally, this means this is a crossing point of the system of equations.
