Answer:
The slope is -7/4
Step-by-step explanation:
∵ 7x + 4y = 10
∵ y = mx + c ⇒ where m is the slope of the line
∴ Re-arrange the equation
∴ 4y = 10 - 7x ⇒ ÷4
∴ y = 10/4 - (7/4) x
∴ y = 5/2 - (7/4) x
∴ The slope is -7/4

Answer:
this is the answer unless you did it backwards
Step-by-step explanation:
3.467406380027739e-4
B= 20°
and c = 160°
b is equal to the given angle, b = 20°
c is 180 - 20 = 160°
