Triangle x y z is cut by line segment c d. line segment c d goes from side x y to side y z. the length of c d is 15, the length of x z is 18, the length of c y is 25, and the length of y d is 20. lines c d and x z are parallel. if and cx = 5 units, what is dz? 2 units 3 units 4 units 5 units

y = 2x + 1

Step-by-step explanation:

Graphing that line, you know that the y-intercept is 1, so you can plot a point at (0,1). Then, knowing the slope (which is 2), you can break it down to:

rise

run

That is also the same as 2/1, meaning go up 2 units, and right 1 unit for each point. However, going backwards, as in down 2 units, and left 1 unit, you can see the other half of the line. By doing so, your first point will be (-1,-1), or point B. So, y = 2x + 1.
