Answer:
y= 2x +7
Step-by-step explanation:
<u>Slope-intercept</u><u> </u><u>form</u><u>:</u>
y= mx +c, where m is the slope and c is the y-intercept.
Given that the slope is 2, m=2.
y= 2x +c
Given that the y-intercept is -7, c = -7.
y= 2x +7

Answer:
s=x/3+10/3
Step-by-step explanation:
Answer:
D(-5,3) and E(-5,1)
Step-by-step explanation:
|AB|² = (-1-5)² + (-6-2)²
|AB|² = 36 + 64
|AB|² = 100
|AB| = 10
AB/DE = 5
|DE| = 10/5 = 2
D(-5,3) and E(-5,1)
|DE|² = (-5+5)² + (3-1)²
|DE|² = 4
|DE| = 2
