Since the graph is a straight line, its equation is of the form;

$y = mx + c$
Where m is the slope and c is the y intercept

We can use any two points on the straight line to find the value of m and c.

Let us use (0,30) and (4,150)

$m = \frac{150 - 30}{4 - 0}$
This simplifies to,

$m = \frac{120}{4} = 30$
Let us substitute the value of m to obtain,

$y = 30x + c$
Substitute any of the points to find c. It is easier to use (0,30).

$30 = 30(0) + c$
$c = 30$
The equation of the graph now becomes,

$y = 30x + 30$
So in 10 weeks Ben will collect,

$y = 30(10) + 30$
$y = 300 + 30$
$y = 330$
Ben will collect 330 papers.

You can also use any two points to find the equation of this line.

Which line segments are equal? How do you know?

Olenka [21]

Answer:

MQ and QP are equal, MO and OP are equal, x=2

Step-by-step explanation:

QO is a perpendicular bisector of MP meaning that Triangle MQP must be isosceles (if at least two of the following, angle bisector, median, or an altitude, coincide in a triangle, that triangle must be isosceles). In this case an altitude and median coincide in triangle MQP. This means that MQ=QP as the triangle is isosceles. And also MO=OP because QO is a median. Now solving for x, 11=4x+3, 8=4x, x=2. Hope this helps!
