Can I get some help please??

1. the y intercept is supposed to be -1 not 1

2a. The slope is a positive slope, its supposed to be a negative one.

2b. Jake wrote a slope of 1/4 instead of -1/4

Step-by-step explanation:

For the second part the point (12,4) is not on the graph.

Plug in the x and y values into the equation y = (-1/4)x - 1

So 12 = (-1/4)(4) - 1

12 = (-1) - 1

12 = -2

12 does not equal 2. Therefore, the point (12,4) does not lie on the graph above.

Hope this helps!

80 the answer is 80

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
