What is the correct equation for the line in slope-intercept form?
vladimir1956 [14]

Answer:

y=-5x+35

Step-by-step explanation:

The equation for a line in slope intercept form is y=mx+b, where m is the slope of the line and b is the y intercept, or where the line meets the y axis.

First, we should calculate the slope of the line. The slope of any line is rise over run. We can select any two points- I will select (6,5) and (4, 15).

We see that the rise is 10 units, because 15-5=10, and the run is -2 units, because 4-6=-2. We have rise over run which is 10/-2, or -5.

So, we find that the m value is equal to -5.

The y intercept is easier to find, it is just where the line meets the y axis. The lines meets the y axis at the point (0,35) so the y intercept is 35.

Thus we have the equation of the line is y=-5x+35.

Hope this helps!

Ivenika [448]
26.2 / 2 = 189.3 / x 

<span>Numerator = distance </span>
<span>Denominator = time </span>

<span>126.2x = (2)(189.3) </span>
<span>126.2x = 378.6 </span>
<span>x = 3 </span>

<span>It will take her 3 hours. 

I really hope this helps!
