Answer:
Y = 1/2x+2
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
We know the slope
y = 1/2x +b
Substitute the point into the equation
0 = 1/2 (-4) +b
0 = -2+b
b=2
Y = 1/2x+2
Let's call the center C. If we draw CT we have an isosceles triangle, two radii for sides, so angle S= angle T. The angle SCT=48 degrees; that's what the arc measure means. So the other two satisfy
S + T + 48 = 180
2S = 132
S = 66
Answer: 66 degress
