(1,5) (2,7) How to find the equation of the line passing through the given points

Mathematics
1 answer:
IceJOKER [234]2 years ago
7 0

Answer:

y = 2x - 3

Step-by-step explanation:

to do this problem, we will use the following formula to find the slope of the line

(y2 - y1) / (x2 - x1)

(1,5) (2,7)

(7 - 5) / (2 - 1)

2 / 1

2 = m

next, we will substitute the slope and one of the points into the slope-intercept form (y = mx + b) and solve for b to find the y-intercept

y = mx + b

7 = (5)(2) + b

7 = 10 + b

-3 = b

finally, we put it all together into one equation

y = 2x - 3

Triangle LMN similar to triangle OPQ find the measure of side PQ round your answer to the nearest 10th if necessary
sergejj [24]

*see attachement for the triangles given

Answer:

PQ = 6.8

Step-by-step explanation:

Corresponding sides of similar shapes or figures are proportional to each other. Since ∆LMN ~ ∆OPQ, the ratio of their corresponding sides would therefore be equal. Thus:

LN/OQ = MN/PQ

LN = 5

OQ = 17

MN = 2

PQ = ?

Plug in the values

5/17 = 2/PQ

Cross multiply

5*PQ = 2*17

5*PQ = 34

PQ = 34/5

PQ = 6.8

sdas [7]

Answer:

A.) Eric rode 2 more miles per week than Kim rode

Step-by-step explanation:

A.) Eric rode 2 more miles per week than Kim rode

B.)Kim rode 3 more miles per week than Erick rode

C.) Kim rode 11 more miles per week than Erick rode

D.) Eric rode 17 more miles per week than Kim rode

Kim rode her biyciclye 135 miles in 9 weeks.

Number of miles Kim rode per week = Total miles travelled / number of weeks

= 135 miles / 9 weeks

= 15 miles per week

Eric rode her biciclye 102 miles in 6 weeks

Number of miles Eric rode per week = Total miles travelled / number of weeks

= 102 miles / 6 weeks

= 17 miles per week

The correct answer is

A.) Eric rode 2 more miles per week than Kim rode

Here’s another one I don’t understand, please give me the answer and explain how you got it
Alexandra [31]

Answer:

39 degrees

Step-by-step explanation:

The angle of a straight line is 180 degrees. This is constant and will never change. You will add 57 and 84 to get 141 degrees for <LMP.  Take 180-141 to get 39 degrees for <PMN
