Write the equation of the line in Point-Slope Form
katrin [286]

17.

The point-slope form:

y-y_1=m(x-x_1)

We have slope=m=8, and the point (-5, -3). Substitute:

y-(-3)=8(x-(-5))\\\\\boxed{y+3=8(x+5)}


18.

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (3, 4) and (15, 10). Substitute:

m=\dfrac{10-4}{15-3}=\dfrac{6}{12}=\dfrac{1}{2}

The point-slope form:

\boxed{y-4=\dfrac{1}{2}(x-3)}

or

\boxed{y-10=\dfrac{1}{2}(x-15)}

A = 8: b = ; C = 10. ​
lara [203]

Answer:

b=6

a^{2}  + b^{2} = c^{2}  \\  {8}^{2} +  {b}^{2}   =  {10}^{2}  \\ 64 +  {b}^{2}  = 100  \\ 100 - 64 =  {b}^{2}  \\ 36 =  {b}^{2}  \\   \sqrt{36}  =  \sqrt{ {b}^{2} }  \\ 6 = b
