Graphing Equation (Algebra)?

Question

Given the x-values, solve for y. Then graph the equation and label the line.


1) y= 2x + 1

x= -1 ____
x= 1 ____

Answer 1

y= 2 (-1) + 1
y= -2 +1
y= -1
m (slope) = 2
intercept (b) = 1
On the graph, put a point at (0,2) and go up one over one.

y= 2 (1) +1
y= 2 +1
y= 3
Put a point at (0,3) and the line should go across.
