The line represented by the equation 2y - 3x = 4 has a slope of.....

S_A_V [24]

2y - 3x = 4
2y = 3x + 4
y = 3/2*x + 2

y = kx + b ==>

k = 3/2 = 1,5

At a dinner, one meal cost $22 and a sales tax of $1.87 was added to the bill.

raketka [301]

Answer:

5.61; 8.5 %

Step-by-step explanation:

Tax = $1.87 per $22 meal

For a $66 meal,

Tax = 66 × 1.87/22

Tax = 3 × 1.87

Tax = $5.61

=====

Tax rate = 1.87/22 × 100

Tax rate = 0.085 × 100

Tax rate = 8.5 %

Write an equation of the line with the given slope and y-intercept,(4,3) and (0,1)

PSYCHO15rus [73]

Answer:

y=1/2x+1

Step-by-step explanation:

First use slope formula.

$\frac{y2-y1}{x2-x1}$

Plug in the information needed.

$\frac{1-3}{0-4}=\frac{-2}{-4}=\frac{1}{2}$

The slope is $\frac{1}{2}$ .

Now, use point-slope formula.

y-y1=m(x-x1)

Plug in the information needed.

y-3=1/2(x-4)

y-3=1/2x-2

y=1/2x+1

The equation of the line in slope-intercept form is y=1/2x+1.

Hope this helps!

If not, I am sorry.
