Answer:

Solution given:

(x1,y1)=(-2,3)

(x2,y2)=(1,9)

we have

equation of line

(y-y1)= $\frac{y2-y1}{x2-x1}$ (x-x1)

(y-3)= $\frac{9-3}{1+2}$ (x+2)

y-3=2x+4

2x-y+4+3=0

2x-y+7=0;is a required equation.

The blue lake trail is 11 3/8 miles long. Gemma has hiked 2 1/3 miles each hour for 3 hours. How far is she from the end of the

sergeinik [125]

Answer:

$4\frac{3}{8}miles$

Step-by-step explanation:

Given that Gemma has hiked 2 1/3 mile each hour for a total of 3 hours, you can multiply her rate by her time to find the total distance:

d = rt or d = 2 1/3(3)

$2\frac{1}{3}=\frac{7}{3}$

Multiply: $\frac{7}{3}*\frac{3}{1}=7miles$

Now, that the total length of the trail, 11 3/8 miles, and subtract the distance that Gemma has gone already:

11 3/8 - 7 = $4\frac{3}{8}miles$

Write the equation in slope intercept form with a slope of 3/4 and passes through (-4,-5)

attashe74 [19]

Answer:Use the slope −2 and the point (−4,−5) to find the y-intercept.

y=mx+b

⇒−5=(−2×−4)+b

⇒−5=8+b

⇒b=−13

Write the equation in slope intercept form as:

y=mx+b

⇒y=(−2)x−13

Hence, the equation of the line is y=−2x−13.
