Question

Write the equation of the line that goes through the point (2,9) and has a slope of 6. Write your answer in proper slope intercept form.

Answer 1

Slope m = 6

Equation y = mx + b = 6x + b

b = y - mx

replace x= 2, y= 9

b = 9 - 6•2 = 9-12 = -3

Then finally ,equation becomes

y = 6x - 3

Answer is y= 6x - 3
