Instructions: Given the vertex of a quadratic function, find the axis of symmetry.
(-1,3)

2y+y=5

add 2y and y

answer: graph 2

step-by-step explanation:

the value of x is 28.2

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.
