Answer:
y+5 = -3(x-1) point slope form
y = -3x-2 slope intercept form
Step-by-step explanation:
First we need to find the slope
m = (y2-y1)/ (x2-x1)
m = (7--5)/(-3-1)
= (7+5)/(-3-1)
= 12/-4
= -3
The slope is -3
Then we can use point slope form to write an equation
y-y1 = m(x-x1)
y--5 = -3(x-1)
y+5 = -3(x-1)
This is in point slope form
Distribute
y+5 = -3x+3
Subtract 5 from each side
y+5-5 = -3x +3-5
y = -3x-2
This is in slope intercept form
Answer:
0.311 miles
Step-by-step explanation:
Convert 16 seconds to hours :
16 /60×60
= 16÷3600
= .004444hrs
Distance = Speed × time
= 70 × 0.00444444
= 0.311 miles
