Answer:
B. y=1/2x+7
Step-by-step explanation:
y2-y1/x2-x1 this finds the slope
Then take one of the coordinates: either (2,8) or (4,9) and plug them into x and y to find b (the y-int)
(2, 8) (4, 9)
(9 - 8)/(4 - 2) = 1/2
y - 8 = 1/2(x - 2)
y - 8 = 1/2x - 1
y = 1/2x + 7
B is the answer
your answer should be 0.80
an open circle means it contains no equal signs.....everything to the left is shaded....means it is less then
x < 1 (thats a less then sign only) ....no equal sign in there
