x_1=1 \\ y_1=-2 \\ \\ x_2=2 \\ y_2=-6 \\ \\
m=\frac{y_2-y_1}{x_2-x_1}=\frac{-6-(-2)}{2-1}=\frac{-6+2}{1}=\frac{-4}{1}=-4 \\ \\
y=-4x+b \\
x=1, y=-2 \\
-2=-4 \times 1+b \\
-2=-4+b \\
-2+4=b \\
b=2 \\ \\
\boxed{y=-4x+2}

Pythagorean theorem help meeeeee!!
agasfer [191]

Answer:

25

Step-by-step explanation:

remember that the pythagorean theorem is a²+b²=c²

so this equation would be:

7²+24²=c²

solve the exponents

49 + 576 = c²

combine like terms

625 = c²

take the radical of each number

√625 = √c²

25 = c

I need help finding x!<br><br> Please show work for both!
Alenkinab [10]
1. Answer x=-5
You would subtract 25 from each side of the equal sign, taking 25 away from 40 and 25 away from 25, isolating the x. So you would then have -3x=15. You would then divide each side by -3, and getting x=-5
