Answer:
reflection over the x-axis bc y changed
Step-by-step explanation:
Answer:
First option, y = 2x - 3
Step-by-step explanation:
Remember the formula for a line is y=mx+b, where m is slope (slope = rise/run) and b is y-intercept (y-intercept is the point that crosses the y-axis)
Since the line on the graph crosses the y-axis at -3, that will be the y-intercept. Starting from that point, find another point. In this case you go upwards 2 units and to the right 1, so your slope will be 2/1 or just 2 .
Hope this helped :)
