Answer:
y = -4x - 7
Step-by-step explanation:
we use the slope intercept formula given by; y = mx + b
b = y intercept, which is when x = 0
m = slope
so they tell us the slope.. we just need to find b - the y intercept.
y = mx + b
plug in your coordinates (-2,1)
1 = -4(-2) + b
1 = 8 + b
1 - 8 = b
-7 = b
put it all together.
y = -4x - 7

Answer:
The two integers are 2 and 3
Step-by-step explanation:
√5
=2.2
Recall that
cos²(<em>x</em>) + sin²(<em>x</em>) = 1
for all <em>x</em>, so that
sin(<em>x</em>) = ± √(1 - cos²(<em>x</em>))
Given that cos(<em>θ</em>) = 4/9 > 0, and
tan(<em>θ</em>) = sin(<em>θ</em>) / cos(<em>θ</em>) < 0
it follows that sin(<em>θ</em>) < 0, so
sin(<em>θ</em>) = - √(1 - cos²(<em>θ</em>)) = - √(1 - (4/9)²) = - √(65)/9
