Question

write an equation of the line with the slope m=-3 that passes through the point (2,3)

Answer 1

y = mx + b plug in x, y, and m and solve for b
3 = -3(2) + b
3=-6 + b
9=b

Answer 2

plug m and b into slope-intercept form
y=-3x + 9

Answer 3

check: 3=-3(2)+9
3=-6+9
3=3

Answer 4

thank you!!

Answer 5

Or you can just plug it into point slope..
\[y-3 = -3(x-2)\]

Answer 6

welcome...great to know both ways!
