Question

19. Find the equation of the line that contains the given points. Write the equation in slope-

intercept form, if possible.
(-5,-5) and (1,7)
Please solve step by step

Answer 1

y = 2x +5

Explanation:

1. use slope intercept for y2 - y1 / x2 - x1 --> 7-(-12) / 1-(-5)

2. solve --> 7-(-12) / 1-(-5) = 2

3. put in slope (2) and a coordinate into equation --> y = mx + b --> 7 = 2(1) + b

4. solve --> 7 = 2(1) + b --> b = 5

5. put the equation together --> y = 2x + 5
