y = - x -
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 6, 1 ) and (x₂, y₂ ) = (2, - 5 )
m = = = -
the partial equation is
y = - x + c
to find c substitute either of the 2 given points into the partial equation
using (- 6, 1 ), then
1 = + c ⇒ c = 1 - = -
y = - x - ← equation of line
Answer:
25 is the answer
Step-by-step explanation:
First off you need to take the square root of both sides and it leaves you with (x)(2x)= 15 then you multiple the x and it gives you 2x^2=15 then you divide by 2 and it gives you 7.5 then you take the square root of that to cancel the x^2 and it gives you x=2.7
1) (given)
2) (corresponding angles)
3) (transitive property)
4) (converse of corresponding angles theorem)
