Write the slope-intercept form of the equation of the line through the given point with the given slope.

Question

1.) Through: (5,-5), Slope= -7/5

2.) Through: (-1,1), Slope= -5

3.) Through: (3,2), Slope= -1

Answer 1

1)

y = -7/5x + b

-5 = -7/5(5) + b

-5 = -7 + b

2 = b

y = -7/5x + 2

2) y = -5x + b

1 = -5(-1) + b

1 = 5 + b

-4 = b

y = -5x - 4

3) y = -x + b

2 = -3 + b

5 = b

y = -x + 5
