Answer:
2
Step-by-step explanation:
Y= mx +c
m is the gradient/slope
m = y2 - y1 / x2 - x1
m = 4-2 / 2-1
m = 2

Step-by-step explanation:
It obviously counting by 4's so this isn't really hard I feel as though I shouldn't give you the direct answer because that is cheating so they are counting by 4's so what do you think that means?
<span>-5√x = -15
</span><span>√x = -15/-5
</span><span>√x = 3
x = 3&2
x = 9
