(-9,7) , (3,3) what is the point - slope form of the equation of the line? what is the slope-intercept form of the equation of the line?

the equation of a line in point-slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 9, 7 ) and (x₂, y₂ ) = (3, 3 )

m = = = -

using (a, b) = (3, 3 ), then

y - 3 = - (x - 3 )

or using (a, b ) = (- 9, 7 ), then

y - 7 = - (x + 9 )

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
