How do you do y=9x+200 Please

So it is in slope intercept form already (y=mx+b)
where m=slope and b=y intercept

so the y intercept is 200 and the x intercept is when y=0 so set y to zero and get
0=9x+200
-200=9x
-200/9=x
x intercept is -200/9

so just plot the points by inputing values for x and getting y values, then graph

so in (x,y) format
(0,200)
(1,209)
(3,229)
(-1,191)
(-2,182)
(-3,173)

and so on

Two cyclists, 112 miles apart, start riding toward each other at the same time. One cycles 3 times as fast as the other, and the
Iteru [2.4K]

Answer:

Speed of a= 21 miles/hr

r = Speed of b= 7 miles/hr

Speed of a = 3r

Step-by-step explanation:

The cyclist are 112 miles apart

Time traveled by two = 4 hours

Speed of a = 3 * speed of b

If a cylcles 3 times More than b, then a will cover 3*distance of b

But speed = distance/time

Time = 4hours

Total distance=112

a = 3b

3b + b = 112

4b = 112

b = 112/4

b = 28 miles

a = 3b

a = 3*28

a = 84 Miles

They bought traveled 4 hours

Speed of a = 84miles/4 hours

Speed of a= 21 miles/hr

Speed of b = 28miles/4 hours

Speed of b = 7 miles/hr

Where is the point of discontinuity of y =<br> -4x+81/x-2<br> ?
Genrish500 [490]

Answer:

x = 2

Step-by-step explanation:

y = \frac{-4x+81}{x-2}

If the denominator is equal to zero , then y is undefined.

this discontinuity can be found by equating the denominator to zero and solving for x.

x - 2 = 0 ⇒ x = 2 is the point of discontinuity
