Step-by-step explanation:
Point slope form is
y - y1 = m(x - x1) where m = slope and (x1, y1) is a point on the line.
Plugging in the given values:-
y - 1.4 = 1.8(x - (-4.5))
y - 1.4 = 1.8(x + 4.5) So the correct choice is A.
Answer:
1.300
Step-by-step explanation:
Since there are 10 hundreds in every thousand, a 4 in the thousands place will represent a value 10 times greater than a 4 in the hundreds place.
Distance =rate/time so your answer is 3 hours first you have to convert meters to kilometers 921000 meters = 921 Km so you have like terms to calculate so your distance becomes 921 Km then divide by the speed 907÷3 = 3 so your answer is 3 hrs
