Question

Find the equation of the straight line with ng gradient and points. b) - 1/2, (2,3)​

Answer 1

`y = -(1)/(2) x+4`

Explanation:

Standard form for equation of line: y = mx + c

where m = gradient or slope

c = y-intercept

From the question we know that,

x = 2

y = 3

m = - 0.5

We will substitute these values into the equation to find c.

3 = (-0.5)(2) + c

3 = - 1 + c

c = 3 + 1 = 4

Therefore the equation of this line is
`y = -(1)/(2) x+4`
