Answer:
B. π/3
Step-by-step explanation:
I calculated it logically
Answer:
y=4x-2
Step-by-step explanation:
if slope is 4, gradient is 4 so y=4x +c
given y intercept of -2,, y=4x -2
c=-2
Angle C=180-(39+28)=180-67=113.
Sine rule:
c/sinC=a/sinA, c=asinC/sinA=23.40 approx.
Answer:
Step-by-step explanation:
1.
(-2,0) (0,-7) y2-y1
-----------------
x2-x1
-7-0= -7
0- (-2)= 2 ------>>> -7/2 =m or slope
2.
y= -7/2x+b to find b u plug in one pair of coordinates for example (-2,0)
and use inverse properties to find b
0 = -7/2(-2) + b
14/2 = 7
0= 7+b
-7 -7
-----------
-7=b
3.
y=-7/2x-7
