Question

What is the equation, in point-slope form, of the line that has a slope of 6 and passes through the point (–1, –8)?

Answer 1

y = mx + b
slope(m) = 6
(-1,-8)...x = -1 and y = -8
now we sub
-8 = 6(-1) + b
-8 = -6 + b
-8 + 6 = b
-2 = b

your equation is : y = 6x - 2

Answer 2

Which of the following is an equation of the line that passes through the point (1, 1) and has a slope of 2?

Answer 3

do it the same way..
y = mx + b
slope(m) = 2
(1,1)..x = 1 and y = 1
now sub
1 = 2(1) + b
1 = 2 + b
1 - 2 = b
-1 = b

your equation is : y = 2x - 1

Answer 4
