Best answer

Equation of linear parent function is y = x

Compare the equation with slope-intercept form y = mx + b.

where m is slope and b is y-intercept.

slope = 1 and y-intercept is 0.

y-intercept is 0, so the line crosses the y-axis at (0, 0)

Using slope find the next point.

Slope = rise/run = 1/1

Start at point (0, 0), move 1 unit up and 1 unit right, then plot the point (1,1).

Draw a line through these points.

Graph :

graph for the equation - x - 2y = 8

Observe the graph it's same as first option.

Option A is correct .
