When you're given a parallel line, that means you know that both lines should have the same slope m.
And you're given a point (x,y) so you plug in the x for

in the equation and y for

in the equation.
Also plug in m because that was given.
y -

= m(x -

)
Then you can simplify the equation to get y = mx + b
Answer:
d = 10
Step-by-step explanation:
A = πr²
81 /π = r²
r² ≈ 25
r = 5
d = 5(2) or 10
8/10 = 4/5 divide each by 2
Answer:
Step-by-step explanation:
Slope of line passing through (2, 7) and (1, -2) = (-2-7)/(1-2) = 9
