Question

What is the equation of the line that passes through the point (1,0) and has a slope of 1

Answer 1

0 = 1(1) + b

b= -1

y = x -1 has slope = 1 and goes through (1,0)

y=mx + b is a standard from for a linear equation with slope = m and b= y intercept.

the slope = m = the coefficient of the x term when the equation is solved for y

y=(1)x + b

y = x+b, plug in the point (1,0) to solve for be

0 = 1+b

b = -1

y = x-1
