Answer:
The missing value is the slope
let me be the slope
m= (3-1)/(0-(-1)) = 2
so y= 2x+3
the missing value is the y-intercept
wich the image of 0 *it's -1
so : y= 3x-1
draw the two functions
you'll find that they intercept at (4;11)
Answer:
3x+4
Step-by-step explanation:
3 dollars per mile = 3x

The answer is z=120 because you need to isolate z and to do that you must multiply each side by 12 and you end up with z=120
Answer:
£168
Step-by-step explanation:
Amount to be shared = 560
Roshana's share = x
Nima's share = 3x
Kate's share = 2 * 3x = 6x
X + 3x + 6x = 560
10x = 560
x = 560 / 10
x = 56
Nima's share = 3x
Nima's share = 3* 56 = £168
