Answer 1

C. x - y = 0

Explanation:

First find write the equation in slope-intercept form, then rewrite to convert to standard form as Ax + By = C.

Equation in Slope-intercept form:

Find m and b

m = rise/run = 1/1 = 1

b = y-intercept = 0 (where the line intercepts the y-axis)

Substitute m = 1, and b = 0 into y = mx + b

Thus:

y = (1)(x) + 0

y = x

Rewrite to convert to standard form.

Thus, the equation in standard form would be:

x - y = 0
