Describe the process for graphing the equation y =-1/2x- 1

Mathematics
1 answer:
AysviL [449]3 years ago
4 0

the formula is y=mx+b

m is the slope

b is the y-intercept form

so the -1 is the y-intercept form. so you need to start at that point on the y axis. then the slope which is -1/2 comes into play. in my school we use rise/run. so from the point you marked at -1 you will go down 1 and to the right 2 points then where you stop is your next point (mark it) keep doing that. also go up the other way from the -1 point. go up 1 and to the left 2. then connect all of your points with a line. I hope this helped.

Cone B is the image of cone A after dilation by a scale factor of \frac{1}{2}
Bogdan [553]

The surface area of cone B is 10 km², and Cone B is the image of cone A after dilation by a scale factor of 1/2

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Cone B is the image of cone A after dilation by a scale factor of 1/2, hence:

Surface area of cone B = 40 km² * (1/2)² = 10 km²

The surface area of cone B is 10 km², and Cone B is the image of cone A after dilation by a scale factor of 1/2

1/2 (b - 10) + 2b = 25
Serggg [28]

Answer:

the answer is 12

Step-by-step explanation:

Simplify both sides of the equation.

12(b−10)+2b=25

(12)(b)+(12)(−10)+2b=25(Distribute)

12b+−5+2b=25

(12b+2b)+(−5)=25 (Combine Like Terms)

52b+−5=25

52b−5=25

add 5 to both sides.

52b−5+5=25+5

52b=30

multiply both sides by 2/5.

(25)*(52b)=(25)*(30)

b=12

The line which passes through -2,5 and 6,8​
babunello [35]

Answer:

y=(3/8)x+5.75

Step-by-step explanation:

y=mx+b

m=slope

b=y-intercept

m=(8-5)/(6+2)=3/8

y=mx+b

5=3/8(-2)+b

5=-3/4+b

b=5.75

y=mx+b

y=(3/8)x+5.75
