Answer:

x= (y+2)/5

Step-by-step explanation:

Let f(x) = y

y = 5x -2

Adding 2 on both sides

y +2= 5x

Divinding by 5 in both sides

(y+2)/5 = x = f*(x)

Therefore,

f*() = (y+2)/5

(0,0)(12,84)
slope = (84 - 0) / (12 - 0) = 84/12 = 7

it goes thru the origin (0,0) therefore, the y int = 0

In y = mx + b form, the slope will be in the m position and the y int will be in the b position.

ur equaton is : y = 7x + 0, which can also be written as y = 7x <==

Eliminate the parameter,t, in the parametric equation, x=6cos t, and y =3 sin t

german

X = 6 cos(t)
y = 3 sin(t)

we can rewrite these equations as:

$\frac{x}{6}=cost(t) \\ \\ \frac{y}{3} =sin(t)$

Taking squares of both equations we get:

$( \frac{x}{6})^{2}=sin^{2} (t) \\ \\ 
( \frac{y}{3})^{2}=cos^{2}(t)$

Adding both the equations, we get:

$\frac{ x^{2} }{36}+ \frac{ x^{2} }{9}=sin^{2}(t)+cos^{2}(t) \\ \\ 
 \frac{ x^{2} }{36}+ \frac{ x^{2} }{9}=1$
