Question

The graph below shows the equation y=2x+4

2
In the space below, describe the effect on this graph if the equation were changed to y=3x+4

Answer 1

Explanation:

If you type this equation onto the graphing calculator you can clearly tell the lines intersect therefore the right answer is the last one.

Answer 2

C. the lines will be intersecting but neither parallel nor perpendicular

Explanation:

changing the x coeficient means you're changing the gradien/ slope. so it will intersecting in one point of y if the x = 0

y = 2x + 4

y = 2(0) + 4 = 4

y = 3x + 4

y = 3(0) + 4 = 4
