Graph the systems of equation on a piece of paper. what is the solution.
y = x-1
y= -2 + 5

a. (0,5)
,4)
c (2,1)
d (3,2)

C

Step-by-step explanation:

Assuming the lines are y = x -1 and y = -2x + 5, set them equal and solve for x.

x - 1 = -2x + 5

3x - 1 = 5

3x = 6

x = 2

Substitute x = 2 into one of the equations to find y.

y = 2 - 1

y = 1

The solution is (2,1).

answer: answer is b.

[m < b = 120º]

step-by-step explanation:

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
