Work out the equation of the line which has a gradient of 1/2 and passes through the point (4,-2)

y= 1/2x-4

Step-by-step explanation:

1/2 and passes through the point (4,-2)

Y=mx+b

-2=1/2(4)+b

-2= 2+b

-2-2=b

-4=b

Y= 1/2x-4

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

the 4th choice is the correct one
