Step-by-step explanation:
After you do what the pic says you take 540 and subtract it from 1800 to see the amount left to pay.
It will take 526.8817.... seconds for the light to reach the planet.
Y= x + 3
1. Find the gradient(slope)
1 - 7 / - 2 - 4
=1
2. Find the y. Intercept ( c )
Y = x + c
Replace by any of the two coordinates given (4 , 7 )
7 = 4 + c
C= 3
Equation => Y = x + 3
Answer:
False
Step-by-step explanation:
the slope is -2/1 AKA -2 so it is negative
Every point on the x-axis has y-coordinate 0.
Let y = 0, and solve for x.
y = -5x + 5
0 = -5x + 5
5x = 5
x = 1
The line crosses the x-axis at x = 1.
