1) n(6;1;-1)=n(A;B;C), point A(2;9;4)=A(x₀;y₀;z₀);
2) common view for a plane according the conditions is: A(x-x₀)+B(y-y₀)+C(z-z₀)=0;
3) after substituted coordinates: 6(x-2)+(y-9)-(z-4)=0; ⇒ 6x+y-z-17=0.
Answer:
B)
Step-by-step explanation:
Slope = -3
Y-intercept = 3
So
Equation is
y = mx+b
Where m is slope and b is y-intercept
y = -3x+3
Answer:
3
Step-by-step explanation:
The equation is written in slope-intercept form.
- 'm' is the slope.
- 'b' is the y-intercept.
<u>3 takes place of 'm' in the equation</u>, so three is the slope of the linear equation.
It increased by 100%.
