Simple,
using

find your slope...

thus, 10=m (slope)
Now, using y=mx+b to find your equation, plug in what you know...
Use any of the 2 coordinates.. (1,5)
5= 10(1)+b
5=10+b
-10 -10
-5=b
Thus, the equation to your line is...
y=10x-5.
The answer is choice A
The line is RS because R and S are on the line.
The plane is RSU because we need at least 3 non-collinear points to form a plane. In this case, point U is not on line RS.
Answer:
5
Explanation: y-intercepts are just numbers that don't have any variables and they can be found on the y axis.
The total cost of the taxi service is the flat free and the total amount that is based on the distance. Let x be this distance. The equation that would best represent the situation is,
1.25 + 0.75x = 14
Solving for x gives the answer of 17. Thus, Henri can afford to travel 17 miles.
