Write the equation of a line in standard form that has x-intercept (P, 0) and y-intercept (0, R).

Rx − Py = PR
Rx + Py = PR
Px − Ry = −PR
Px − Ry = PR

Correct option: second one -> Rx + Py = PR

Step-by-step explanation:

we can model the equation of a line with the following equation:

y = ax + b

where a is the slope and b is the y intercept.

From the y-intercept (0,R), we have that:

R = a*0 + b

b = R

From the x-intercept (P,0), we have that:

0 = aP + b

aP = -R

a = -R/P

So we have that:

y = (-R/P)x + R

Multiplying both sides by P, we have:

Py = -Rx + PR

Rx + Py = PR

Correct option: second one

Rx + Py = PR

Step-by-step explanation: I took the test and the 4th option was incorrect. When I retook it I got it correct with option 2.

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
