Find the gradient and the intercept shown by the straight line 2x + 3y = 6

sveta [45]

Answer:

$\sf gradient =\dfrac{-2}{3}\\\\ y -intercept = 2$

Step-by-step explanation:

<h2>Equation of the line in slope intercept form:</h2>

$\sf \boxed{\bf y = mx +b}$

Here m is the slope or gradient and b is the y-intercept.

Write the given equation in slope-intercept form.

2x + 3y = 6

3y = -2x + 6

$\sf y =\dfrac{-2}{3}x +\dfrac{6}{3}\\\\ y = \dfrac{-2}{3}x + 2$

$\sf gradient =\dfrac{-2}{3}\\\\ y -intercept = 2$

Brut [27]

Answer:

x=√y+4 or x=−√y+4

Step-by-step explanation:

Step 1: Add 4 to both sides.

x2−4+4=y+4

x2=y+4

Step 2: Take square root.

x=√y+4 or x=−√y+4
