<u>Step-by-step explanation:</u>
Blue line:
y-intercept (b) = -2
slope (m) is 3 up, 1 right = 3
shading is above
⇒ y ≥ 3x - 2
Yellow line:
y-intercept (b) = 3
slope (m) is 1 up, 2 right =
shading is below
The answer is true.
Step-by-step explanation:
To find the points all lie on the same line, we need to substitute the points in the equation of the line, to determine if the values on both sides of the equation are equal.
Substituting the point in the equation of the line, we get,
Thus, the values on both sides are equal. The point lie on the same line.
Substituting the point in the equation of the line, we get,
Thus, the values on both sides are equal. The point lie on the same line.
Substituting the point in the equation of the line, we get,
Thus, the values on both sides are equal. The point lie on the same line.
Thus, all the three points lie on the same plane.
Hence, the answer is true.
