Question

A line passes through the point (2, 3) and has a slope of -8. Write an equation for this line.

Answer 1

Explanation:

to find the equation of this line you use the equation of the slope intercept which is y-y1= m (x-x1)

y-3=-8(x-2)

y-3=-8x+16

y=-8x+16+3

y=-8x+19

I hope this helps

Answer 2

y = -8x+19

Explanation:

The slope intercept form of a line is

y = mx+b where m is the slope and b is the y intercept

y = -8x+b

Substitute the point into the equation

3 = -8(2)+b

3 = -16+b

Add 16 to each side

3+16 = b

19 = b

y = -8x+19
