What is the equation of the graphed line in point-slope form?
SSSSS [86.1K]
First, we find the slope
(4,0)(0,-3)
slope = (-3 - 0) / (0 - 4) = -3/-4 = 3/4

there can be 3 possible answers for this..
y - y1 = m(x - x1)
slope(m) = 3/4
using points (4,0)...x1 = 4 and y1 = 0
now we sub
y - 0 = 3/4(x - 4) <== this is one answer

y - y1 = m(x - x1)
slope(m) = 3/4
using points (0,-3)...x1 = 0 and y1 = -3
now we sub
y - (-3) = 3/4(x - 0) =
y + 3 = 3/4(x - 0) <== here is another answer

y - y1 = m(x - x1)
slope(m) = 3/4
using points (-4,-6)...x1 = -4 and y1 = -6
now we sub
y - (-6) = 3/4(x - (-4) =
y + 6 = 3/4(x + 4) <=== and here is another answer

How do you answer this question 3/4b +10=20
noname [10]
1) move the 10 over
So it becomes
3/4b = 10
2) multiply everything by 4 to get rid of the denominator
2b = 40
3) divide both sides by 2
b = 20

A car bus travels at a speed of 45 km/h. How far will it travel in 36 minutes?​
tensa zangetsu [6.8K]

Correct Question:

A car/bus travels at a speed of 45 km/h. How far will it travel in 36 minutes?

(Note- Corrected part is written in bold.)

Solution:

\sf Speed = 45 \: km/h

\sf Time=36 \: mins

\sf   = \frac{36}{60} \:  hour \: (Since  \: we  \: know,1 \: hour \:  = 30 \: mins

\sf =  \frac{3}{5}  \: hour

\sf \: Distance = Speed \times Time

\sf =  \: 45 \times \frac{3}{5}  \: km

\sf   = \frac{45 \times 3}{5}  \: km

\sf \: Distance=27 \: km

  • Hence, a car/bus travels 27 km in 36 mins.
