Answer:
y=-3x-1
Step-by-step explanation:
<u>Slope-intercept format:</u>
y = mx+b
m = slope
- In this case, the slope is -3
b = y-intercept
- In this case, the y-intercept is -1
Now we plug it in to get the equation:
y=-3x-1
I hope this helped!

The answer would be 7.225.
Answer:
m∠ADC = 132°
Step-by-step explanation:
From the figure attached,
By applying sine rule in ΔABD,


sin(∠ADB) = 
= 0.74231
m∠ADB = 
= 47.92°
≈ 48°
m∠ADC + m∠ADB = 180° [Linear pair of angles]
m∠ADC + 48° = 180°
m∠ADC = 180° - 48°
m∠ADC = 132°
Yes because 84+45 is 129 and 3(28+15) is 129
