Question

Please help me A line that includes the point (3, 3) has a slope of 4. What

is its equation in slope-intercept form?

Answer 1

Answer:You can do this two ways: Either use the slope intercept form

y = mx + b with slope m=-2 so y = -2x +b

From that use x=5, y = -3 to solve for b

-3 = -2(5) + b

-3 = -10 + b

10-3 = b

7 = b

Your equation is: y = -2x + 7

OR

Use the point slope formula: y - y1 = m(x-x1)

with m = -2, (x1, y1) = (5,-3)

y-(-3) = -2(x-5)

y + 3 = -2x + 10

y = -2x + 10 - 3

y = -2x + 7
