Answer:
y-intercept (0, 8)
Step-by-step explanation:
Plug in (1,4) --> (x,y) and solve for b (y-intercept):
y = -4x + b
4 = -4(1) + b
4 = -4 + b
b = 8
Therefore the y-intercept is (0, 8)
Lets solve for both possibilities.
A. (2,4)
<span>-3x+5y=2x+3y
-3(2)+5(4)=2(2)+3(4)
-6+20=4+12
14</span>≠16
Incorrect
B. (3,3)
<span>-3x+5y=2x+3y
-3(3)+5(3)=2(3)+3(3)
-9+15=6+9
6</span>≠15
Incorrect
Neither ordered pairs work for the equation.
Answer=D
Answer:
0.546 , -4.71
Step-by-step explanation:
Given:
An angle's initial ray points in the 3-o'clock direction and its terminal ray rotates counter -clock wise.
Here, Slope = tan\theta
If θ = 0.5
Then, Slope = tan(θ) = tan(0.5) = 0.546
If θ = 1.78
Then, Slope = tan(θ) = tan(1.78) = - 4.71
The expression (in terms of θ) that represents the varying slope of the terminal ray.
Slope = m = tanθ, where θ is the varying angle
I think its b but i am not surely sure so you might want to check with someone else
