Aline passes through (1,5) and (-2,-1).find the slope-intercept form of the equation of the line.then fill in the value of the slope, m, and the value of the y-intercept, b, below

(1,5) 5 - (-1) = 6 slope = 6/3 = 3

(-2,-1) 1 - (-2) = 3

y = 3x + b

5 = 3 + b

b = 2

y = 3x + 2

slope = 3 = m

y-intercept = 2 = b

y = 3x + 2

2.8 hours and the phone will be fully charged.

Step-by-step explanation:

16% per 30 minutes = 32% per hour

(100-10) ÷ 32 = the amount of hours it will take to fully charge the battery.
