Equation you asked: 4x +4y = 20, Rewritten equation: -1x + 5
hope this helps.
When finding slope the answer is always going to be rise/run so in this case,
#1 would be 1/2 (bc it goes up one and right 2)
#2 we have a rise of 3 and a run of 3 leaving our slope to be 3/3 simplified simply being 1
another trick you could use is dividing the denominator by the numerator
We have been given a chord and tangent to a circle. We have been minor arc measure that is equal to
.
Since we know that angle formed by a secant and tangent of circle is half of the measure of intercepted arc.

We can find intercepted arc by subtracting minor arc measure from 360 degrees because minor and major arcs add up to 360 degrees.
Now we will plug given values in our formula,

Therefore, the measure of d is 121 degrees.
Answer:
b
