Write in slope intercept form an equation of the line that passes through the given points. (-1,7) , (3,-1)

Tcecarenko [31]

Answer! :

y = -2x + 5

Step by Step! :

slope intercept form:

y = mx + b

m being slope, b being the y intercept.

To find the slope, use this equation:

y^2 - y^1 / x^2 - x^1

Plug in your points.

(-1) - (7) / (3) - (-1)

-8 / 4

-2 is your slope! (y = -2x + b)

To solve for b, plug in any one of your points and solve for b. Let's use (3, -1)

-1 = -2(3) + b

-1 = -6 + b

5 = b

Your new equation is...

y = -2x + 5

Option B

2 times the length of Noah's bike ride was Mai's bike ride

<h3><u>Solution:</u></h3>

Given that Mai biked 7 and 1/4 miles today and Noah biked $3\frac{5}{8}$ miles

We have to find how many times the length of Noah's bike ride was Mai's bike ride

Let "a" be the number that denotes how many times the length of Noah's bike ride was Mai's bike ride

From given information,

Distance biked by Mai = $7\frac{1}{4} \text{ miles}$

Distance biked by Noah = $3\frac{5}{8} \text{ miles}$

So to find how many times the length of Noah's bike ride was Mai's bike ride, we can frame a equation as:

"a" times distance biked by noah is equal to distance biked by mai

$\text{ Distance biked by Mai } = a \times \text{ Distance biked by Noah }$

<em><u>Substituting the known values we get,</u></em>

$7\frac{1}{4} = a \times 3\frac{5}{8}\\\\\frac{4 \times 7+1}{4} = a \times \frac{8 \times 3 +5}{8}\\\\\frac{29}{4} = a \times \frac{29}{8}\\\\\frac{1}{4} = \frac{a}{8}\\\\a = 2$

Thus 2 times the length of Noah's bike ride was Mai's bike ride
