Question

Which equation represents a line that passes through (4, 5) and has a slope of 22

Answer 1

y=22x-83

Explanation:

To find equation plug the numbers in y=mx+b form

5=22(4)+b

5=88+b

Minus 88 on both sides

-53=b

So equation is:-

Y=22x-83

Answer 2

y = 22x - 83

Explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given m = 22, then

y = 22x + c ← is the partial equation

To find c substitute (4, 5) into the partial equation

5 = 88 + c ⇒ c = 5 - 88 = - 83

y = 22x - 83 ← equation of line
