Problem 9

This function is linear because each time x goes up by 1, y goes up by 3. This represents a slope of rise/run = 3/1 = 3. The slope is the rate of change.

=====================================================

Problem 10

We have y decreasing at first (y = 4 to y = 1 to y = 0), but then y increases after y = 0. This is sufficient info to prove the function isn't linear. A linear function either always increases, always decreases, or is constant (aka a flat horizontal line).

=====================================================

The graph on the left has us start with (0,4) as the y intercept, due to b = 4. We then drop down 2, and move to the right 3 to get to the next point (3,2). The "down 2, right 3" motion is directly because of the slope m = -2/3.

The graph of the right has the points (-2,0) and (0,3) as the x and y intercepts in that order. This is from a = -2 and b = 3 given by your teacher. We only need 2 points to form a straight line.

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

50-38=12
