Question

The point-slope form of the equation of a line that passes through points (8, 4) and (0, 2) is y – 4 = (x – 8). What is the slope-intercept form of the equation for this line?

y = x – 12
y = x – 4
y = x + 2
y = x + 6

Answer 1

Change y – 4 = (x – 8) into slope-intercept form, y = mx + b.

y – 4 = (x – 8) => y = 4 + x - 8 => y = x - 4 (answer)
