Write the equation of a line through (2,2) and with both x intercept of (a,0) and y intercept (0,b).

Question

(a≠0,b≠0). Make sure to fine y intercept containing a. Don’t just write b.

Answer 1

Well then the slope is (b-0)/(0-a) = -b/a

In point slope form:

y-2 = (-b/a)(x-2)

y = (-b/a)x + 2(b/a) + 2

y = (-b/a) x + [ 2(b/a)+2]

The entire expression in bold is the y-intercept
