It’s the third one 9(5+1)
As 9 x 5 = 45
9x 1 = 9
To stretch it vertically, you'll need a coefficient greater than 1 in front of the x. If you want to flip the graph over the x axis that coefficient needs to be negative. So it can only be D
B i hope it helps if not sorry
Consider the line y = 2x + 1, shown at the right. Notice that this slope will be the same if the points (1,3) and (2, 5) are used for the calculations. For straight lines, the rate of change<span> (slope) is constant (always the same). For every one unit that is moved on the x-axis, two units are moved on the y-axis.hope this helped. </span>
y+43°= 180°( straight angle)
=>y= 180°-43°
=>y=137°
