find the equation

Question

Find the equation of the line satisfying the given conditions. Write the equation in the form y = mx + b.

Through (−5, 6) and (−1, −2)

Answer 1

Answer 2

Per the other two answers, slope is -2 (m in the equation)

y = mx + b. Find b by substituting either of the ordered pairs for x and y.

6 = -2(-5) + b

b = 6 - 10 = -4

y = -2x - 4

Answer 3

slope = (-2-6) / (-1-(-5)) = -8 / 4 = -2

Equation of line: y - 6 = -2(x - (-5))

Solve for y.

Answer 4

line through (-5,6) and (-1,-2) has slope = ((6+2)/(-5+1) = -8/4 = -2

y = -2(x+1) -2

y = -2x -4 in slope intercept form, slope = -2, intercept = -4
