Identify the graph of the equation. What is the angle of rotation for the equation? 21x^2 - 8 times radical (3xy) + 13 y^2 = 225

it’s supposed to be -4+45=41

step-by-step explanation:

d

step-by-step explanation:

the two points from this line are   (0,4)   & (2,-2)

we can call

now, lets find the slope (m):

now finding b (the y intercept). this is the point at the y-axis where the line cuts the axis. looking at the graph, it is y = 4. so the point is 4. hence b = 4

the slope-intercept form is given by  

putting the points, we have:

d is the correct answer.
