What is the slope intercept from of the equation of the line that passes through (7, -5) and (3, -9) a y=x+12 b y=x-12 c y=x+5 d y=x—4

B.

Step-by-step explanation:

First, find the rate of change [slope]:

Then use the Slope-Intercept Formula instead of the Point-Slope Formula because you get it done faster that way. It does not matter which ordered pair you choose:

−9 = 3 + b

−12 = b

________________________________________________________________________________________________

−5 = 7 + b

−12 = b

** You see? I told you it did not matter which ordered pair you choose because you will ALWAYS get the exact same result.

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
