Question

For the equation x − y + 1 = 0; the values of slope (m) and y-intercept (c) are ______.

Options

• m = 1, c = 1

• m = −1, c = 1

• m = 1, c = −1

• m = −1, с = −1

Answer 1

For the equation x − y + 1 = 0; the values of slope (m) and y-intercept (c) are m = 1, c = 1.

Explanation:

Rewriting the equation x − y + 1 = 0 in slope-intercept form (y = mx + c):

y = x + 1

Comparing this with y = mx + c, the slope is m = 1 and the y-intercept is c = 1.
