Question

write an equation for the line passing through B(0,3) and C(-3,4)

Answer 1

first we need to find the slope by using the slope formula.
slope(m) = (y2 - y1) / (x2 - x1)
(0,3)...x1 = 0 and y1 = 3
(-3,4)...x2 = -3 and y2 = 4
now we sub
slope(m) = (4 - 3) / (-3 - 0)
slope(m) = 1/-3 or -1/3

now we use y = mx + b...we know the slope, but we have to find b (the y intercept)
slope(m) = -1/3
choose either of your points...I choose (0,4)...x = 0 and y = 4
now we sub
4 = -1/3(0) + b
4 = b

so our equation is : y = -1/3x + 4

You are making this so much easier to understand. haha thank you :)
