Identify the equation of the graph shown. a) y = 4x + 5 b) y = - 4x + 5 c) y = 4x - 5 d) y = - 4x - 5

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.

shorter then the tree

for every positive x value, the y value must be greater than 1.

for every negative x value, the y value must be less than 1.

in your options, you can check to see that one of these two criteria is met. if neither are met, then it is not on a slope with positive line.
