Question

Write the point-slope form of the equation of the line that passes through the point (1, 3) and has a slope of 2. Include 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, m is the slope and b is the vertical intercept. When given 2 points and the slope, enter the info into the equation, 3 = 2(1) + b and solve for b. 1×2=1. divide two from both sides cancelling out two and dividing 2 from 3. So then b = 3/2. Re-enter the info back into the equation. y = 2x + 3/2. Some assignments may ask you to put into a decimal. Otherwise keep it as a fraction
