Connelly has 1 / 4 of a cup of water. Ryan has 2 / 5 of a cup of water. Grayson has 0.4 less than 2 times Connelly's amount of w

Katarina [22]

We will make ''X'' the result that we are searching for
and ''Y'' how much water Grayson has

So we have : X = Y + 2/5

and : Y = 2/4 - 0.4 = 1/2 - 4/10 = 1/10

So X = 1/10 + 2/5 = 5/10 = 1/2 0f a cup

What is the slope of the line?

goldenfox [79]

$\frac{3-2}{2-4} = \frac{1}{-2} = -0.5$

slope = $\frac{1}{-2}$ or -0.5

What is a correct equation for the line passing through the point (-2,1) and having slope m=1/2

frez [133]

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

m - slope

We ahve the slope m = 1/2 and the point (-2, 1). Substitute:

$y-1=\dfrac{1}{2}(x-(-2))$

$y-1=\dfrac{1}{2}(x+2)$ - point-slope form

Covert to the slope-intercept form (y = mx + b):

$y-1=\dfrac{1}{2}(x+2)$ use the distributive property

$y-1=\dfrac{1}{2}x+1$ add 1 to both sides

$y=\dfrac{1}{2}x+2$ - slope-intercept form

Convert to the standard form (Ax + By = C):

$y=\dfrac{1}{2}x+2$ multiply both sides by 2

$2y=x+4$ subtract x from both sides

$-x+2y=4$ change the signs

$x-2y=-4$ - standard form

Convert to the general form (Ax+By+C=0):

$x-2y=-4$ add 4 to both sides

$x-2y+4=0$ - general form
