To truly understand how to graph this line, you need to begin at the basic foundation of a general equation. So, the standard form for a line is called slope intercept form, which mathematically equates to y = mx + b. M represents your slope (rise/run OR solved by formula) and B represents your y-intercept, which is determined with an equation or, if you have a graph, it's the point in which your line crosses the y-axis.

So, to graph your line, use what you know about the form. 2 is going to be your y-intercept and 1 will be your slope. You know that 1 is the slope because it's widely accepted that if a variable (x) is lacking a coefficient, it's just one. In other words, your line is y = 1x + 2.

Now you know where to start, place your pencil (or rather, digital pencil) on the coordinates (0, 2): the y-intercept. Then, since you know slope is 1, move up one unit and then to the right one unit. You do this because slope = rise/run, therefore, 1 = 1/1. You'll continue to move up one & right one until you reach the end of your graph. But wait, you aren't done yet. As you may have already discovered, the line if heading in a general direction at this point & it only takes up half of the graph. To draw the rest, go back to your original point (0, 2). Then, move down one & to the left one. This is because -1/-1 is also equal to 1, so the slope remains constant.

At this point, your line should be graphed completely & you should have a simple understanding on graphing equations. If you need further help, let me know.

The two points are -2 and positive 2 that’s how you graph

Jack bought 50 lbs of clay for his art projects. He used 13.2 lbs to make a sculpture, and 0.72 lbs for each mug. How many mugs

KIM [24]

Given :

Jack bought 50 lbs of clay for his art projects. He used 13.2 lbs to make a sculpture, and 0.72 lbs for each mug.

To Find :

How many mugs did Jack make if he had 28.88 lbs of clay left over.

Solution :

Clay required to make 1 mug, r = 0.72 lbs.

Amount of clay left after making sculpture is, T = 28.88 lbs.

Now, number of clay mug Jack can make is :

$n = \dfrac{28.88}{0.72}\\\\n= 40.11$

Since, number of mug cannot be in decimal, so we take the floor value.

Therefore, number of mug that can be prepared is 40 .

2 x [(29-6)-[(6+5)] please show work!

Anika [276]

Answer:

Not sure, read steps.

Step-by-step explanation:

First do the ()

29 - 6 = 23

6 + 5 = 11

SUBTRACT THE INTEGERS:

23 - 11 = 12

So, 2 x 12 = 24.

SAT reading and writing section scores of a random sample of twenty 11th-grade students in a certain high school are given below

kvasek [131]

Answer:

The value of test statistics is 25.

Step-by-step explanation:

We are given below the SAT reading and writing section scores of a random sample of twenty 11th-grade students in a certain high school;

380, 520, 480, 510, 560, 630, 670, 490, 500, 550, 400, 350, 440, 490, 620, 660, 700, 730, 740, 560

Let $\sigma$ = population standard of the reading and writing section SAT score of the students in this school

So, Null Hypothesis, $H_0$ : $\sigma \leq$ 100 {means that the reading and writing section SAT score of the students in this school is lesser than or equal to 100}

Alternate Hypothesis, $H_A$ : $\sigma$ > 100 {means that the reading and writing section SAT score of the students in this school is higher than 100}
