Slope-intercept form: y = mx + b [m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis]
For lines to be parallel, they have to have the same slope
y = x + 7
m = 1 So the parallel line's slope is also 1
y = mx + b
y = x + b To find b, plug in the point (8, 10) into the equation
10 = 8 + b Subtract 8 on both sides
2 = b
y = x + 2
