Drag equations to each row to show why the equation of a straight line is y = 2x + 5, where 2 is the slope and 5 is the y-intercept.

2-3 6. use your equation to find how high tyler will have to climb to scale the peak. (4 points: 2 points for correctly substituting values, 2 points for the correct height)

Which pair of lines is parallel? a. y=4x+1 and y+4=5 b. y=-2+x and 2y-2x=-2 c. y=1/4x + 2 and y-2=1/2x d. y=1/5x+1 and 5y+x= 10

Solve the system of equations. y= 2x y= x^2 - 15
