Question

Write the point-slope form of the line that passes through (1, -5) and is parallel to a line with a slope of 1. Include all of your work in your final answer. Type your answer in the box provided or use the upload option to submit your solution

Answer 1

Y=mx + b

Since this line is // to the one with a slope = 1, that means m = 1, hence 

y=x + b. Now let's calculate b. The graph passes by A(1,-5), you replace x and y by their related coordinates:

-5 = 1 + b → →b = -6

Final linear equation ; y = x -6
