Determine the slope of the line that contains the points A(0, 2) and B(7,3). *

IgorC [24]

<h3>Given points:-</h3>

A (0,2)
B (7,3)

We know that

${\boxed{\sf Slope_{(m)}=\dfrac {y_2-y_1}{x_2-x_1}}}$

Substitute the values

$\qquad\quad {:}\longrightarrow\tt m=\dfrac {3-2}{7-0}$

$\qquad\quad {:}\longrightarrow\tt m=\dfrac {1}{7}$

$\therefore \sf Slope\:of\:the\:line\:is\:\dfrac {1}{7}$

To paint a house, a painting company charges a flat rate of $500 for supplies plus $50 for each hour of labor. What is the slope

Nataly_w [17]

The slope of the line is 50. You can try looking at the equation, which is

y=50x+500

500 is your y-intercept, and is where the cost starts.

50 is your slope, since the cost goes up by $50 every time.

x is how many hours, which determines how many $50s there are.

I hope this helps. All in all, the slope is 50.

Look at photo bellow it has the question that needs to be answered

kirza4 [7]

Answer:

The jar contains 132 grams of zinc

Step-by-step explanation:

The ratio of zinc to copper is 4:15, if there were 495 grams of copper, then that means the ratio was multiplied by the quotient of 495 and 15, which is 33. 33 * 4 is 132, so that is the total amount of zinc in the jar.
