Answer:
y=-2x+7
Step-by-step explanation:
Slope is y(2)-y(1)/x(2)-x(1)
I chose (1,5)(0,7) as my two points and got -2 as my slope
Then, I got (0,7) as my y-intercept because it was in the table.
So, the equation is y=-2x+7
(hope this helps :P)
Answer:
C
Step-by-step explanation:
Given
x² - 3x - 12 = 0 ( add 12 to both sides )
x² - 3x = 12
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- )x + = 12 +
(x - )² = ( take the square root of both sides )
x - = ± = ± ( add to both sides )
x = ±
Then
x = + ≈ 5.27 ( to the nearest hundredth )
x = - ≈ - 2.27 ( to the nearest hundredth )
