Find the slope of line passing through the two points, (3, -4) and (1, 2).

mariarad [96]

Answer:

m = -3

Step-by-step explanation:

The formula for slope is $m=\frac{y2-y1}{x2-x1}$

So use the x's and y's from the given points to solve for m

(3, -4) (1, 2)

$m=\frac{2-(-4)}{1-3}$

$m= \frac{6}{-2}$

$m=-3$

Solve 2(y – 3) = 1.2 – y.

Ne4ueva [31]

First write down your equation. 2(y-3)=1.2-y. the distribute your 2. 2 times y is 2y and 2 times -3 is -6. now you have 2y-6=1.2-y. bring your y to the other side of the equation with the opposite sign and do the same with your 6. you have 2y+y=1.2+6. combine the like terms and constants. now you have 3y=7.2. divide bother sides of the equal by 3 to get y alone. 3y/3= 7.2/3. your answer is y=2.4.

A=1/2ab
Replace the variables with their value
15=1/2(3/2)b
Multiply 1/2 and 3/2
$\frac{1}{2} \times \frac{3}{2 } = \frac{3}{4}$
15=3/4b
Divide 3/4 on both sides
15/(3/4) is the same thing as
$\frac{15}{1 } \times \frac{3}{4} = \frac{45}{4}$
45/4=b
