Question

Which equation has a slope of 1/2 and passes through the point (1.2)?

Answer 1

Answer:

The answer is

$x - 2y + 3 = 0$

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of a line given a point and slope we use the formula

y - y1 = m(x - x1)

where

m is the slope

( x1 , y1) is the point

From the question the point is ( 1 , 2) and the slope is 1/2

Substitute the values into the above formula and solve for the equation

That's

$y - 2 = \frac{1}{2} (x - 1) \\ 2y - 4 = x - 1 \\ x - 2y - 1 + 4 = 0$

We have the final answer as

$x - 2y + 3 = 0$

Hope this helps you
