through: (3,-1), perp. to y = -x + 1
5

The answer is y = -5/3+4

Step-by-step explanation:

alright so first we find the reciprocal of 3/5 because it is perpendicular

which is -5/3

we then create an equation and solve for b (y-int) by substituting our coordinates (3, -1)

Sub x and y and isolate b

y = -5/3x + b

-1 = -5/3(3) + b

-1 = -15/3 + b

-1 = -5 + b

+5 +5

4 = b

equation

y = -5/3x + 4

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

answer: x=3 and y=4
