Question

Use the point and the slope to graph each line. write the equation of the line:

The line passes through point (1, -1) and is parallel to line that has a slope 1.

The Equation of the line is..........

Answer 1

Parallel lines have equal slopes so

• m=1

Passes through. (1,-1)

Equation in point slope form

• y-y1=m(x-x1)
• y+1=1(x-1)
• y+1=x-1
• y=x-2

Answer 2

y = x - 2

Explanation:

b = y-(m)(x)

b = -1-1 = -2

y = x-2
