Answer:

I would say it's -0.8

Step-by-step explanation:

Since 3 is pretty far, I'm assuming -2 is at the left end of the line, so -.8 seems like the most reasonable answer.

To solve this problem we can make a proportion.
6      5
-- = ---
10    x

to solve this proportion we can cross multiply and divide.
5 times 10 is 50.  divided by 6 is 8.3
it will take her 8.3 minutes to run 5 laps

What is the equation of the line that passes through the point (−4,−3) and has a slope of \frac{3}{4}
yawa3891 [41]

Answer:

y = \frac{3}{4} x

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = \frac{3}{4} , then

y = \frac{3}{4} x +c ← is the partial equation

To find c substitute (- 4, - 3) into the partial equation

- 3 = - 3 + c ⇒ c = - 3 + 3 = 0

y = \frac{3}{4} x ← equation of line

9. Todd makes $9.25 per hour plus a $50 bonus. Todd made $235 this week.
Daniel [21]

Answer:

20 hours

Step-by-step explanation:

use this linear equation

y = 9.25x + 50

plug in 235 for y and solve for x

235 = 9.25x + 50

185 = 9.25x

20 = x

so he worked for 20 hours

hope this helped <3
