Answer:
y=2x+10
Step-by-step explanation:
In line equations its helpful to write your line in the form y = ax + b. This helps because a is always the gadient of the line and b is always the y intercept.
In this case it is y=2x+3
All parallel lines have the same gradient. The gradient of this line = 2.
If the line crosses the x axis at x=-5, then when x =-5 y = 0.
If you put all this in the form y =ax + b you get 0 = 2(-5) +b
So all you need to do to find b is rearrange. b = 10.
Therefore your line has gradient 2 and y intercept 10.
y = 2x + 10
Answer:
Step-by-step explanation:
a. 0.31
Answer:
Step-by-step explanation:
B. 6 km
You have to draw it so you can better process it. From there it's just the Pythagorean theorum.
a²+b²=c²
6²+b²=10²
(10 is c because it's the hypotenuse)
64+b²=100
100-64=36
√36 = 6
