What is the equation for a line that passes theough (-1, -5) and (-3, -7)?

y=x-4

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-7-(-5))/(-3-(-1))

m=(-7+5)/(-3+1)

m=-2/-2

m=1

y-y1=m(x-x1)

y-(-5)=1(x-(-1))

y+5=x+1

y=x+1-5

y=x-4

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.

do practice tests.

note: the best i know.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
