Answer:

Step-by-step explanation:
The given equation is:

To find the point where this line intersect the y-axis, we put x=0 into the given equation.
When x=0, we have
.
This implies that; y=5.
The y-intercept is (0,5).
Comparing (0,5) to (0,b), we can conclude that; b=5

Answer: The answer could be C because is the image of the rotation by 90 degrees clockwise. I hope its right
Answer:
arc GM = 77°
Step-by-step explanation:
full circle = 360°
arc GMH = arc GNJ, so:
arc GMH = (360°- 52°)/2 = 154°
because line MP is perpendicular to line GH, arc GM = arc MH
arc GM = 154°/2 = 77°
It is calculations because with measurements you would just put a decimal. The calculator uses improper fractions.
