Write each equation in slope-intercept form (3,4); and (-6,-2)
Alborosie

Answer:

y = 2/3x + 2

Step-by-step explanation:

Slope intercept form is y=mx+b where m is the slope and b is the y intercept.

Given 2 points you can find the slope using (y-y1)/(x-x1)

m = (-2-4)/(-6-3) = -6/-9 = 2/3

To find b use one of the points and m and plug into the slope intercept form and then solve for b.

y=mx+b

4=2/3(3) + b

4=2 + b

b=2

Now we can write the final equation as : (plug m and b back in)

y = 2/3x + 2

Brayden is working two summer jobs, making $18 per hour lifeguarding and making $9 per hour clearing tables. In a given week, he
spin [16.1K]

Answer:

2 hours.

Step-by-step explanation:

Money earned for 14 hours of life-guarding = 14*18 = $252.  If he worked another 5 hours  to make the maximum of 19 he would earn 252 + 5*9

= $297  but he wants to work a minimum of hours for  a minimum of 270.

Thus we have the inequality:

252 + 9x ≤ 270

9x  ≤  18

x  ≤ 2.

So the number of hours he must do clearing tables = 2.

margaret says there is not enough information to show WXYZ is a parallelogram. Explain why Margaret is incorrect
alisha [4.7K]

Margaret claim is incorrect because the shape has equal and parallel opposite sides

<h3>Parallelograms</h3>

A parallelogram is a shape that has the following properties

  • The shape is a polygon
  • Opposite sides are parallel
  • Opposite sides are congruent

From the figure, we can see that the shape has the above properties.

Hence, Margaret's claim is incorrect.

This is so, because the shape has equal and parallel opposite sides.
