What is an equation of the line that passing through the points (-2, -5) and (4, 7) ?
monitta

Answer:

y=2x-1

Step-by-step explanation:

Use the slope-intercept formula: y=mx+b where m is slope and b the y-intercept.

(-2,-5)(4,7)

Use the slope formula for when you have two points:

\frac{y(2)-y(1)}{x(2)-x(1)}=\frac{rise}{run}

Rise over run is the change in the y-axis over the change in the x-axis. Insert values:

\frac{7-(-5)}{4-(-2)}

Simplify parentheses (negative+negative=positive)

\frac{7+5}{4+2}

Simplify

\frac{12}{6}=2

2 is the slope:

y=2x+b

Now use one of the points to find the y-intercept by substituting the x and y values into the equation. Solve for b:

(4,7)

y=2x+b\\7=2(4)+b

7=8+b\\7-8=8-8+b\\7-8=b\\-1=b\\b=-1

The y-intercept is -1. Insert into the equation. Change the + symbol to -:

y=2x-1

Done.

If m=2,n=5 and y =3, evaluate
svlad2 [7]

Answer:

here you go :)

Step-by-step explanation:

Replace the variables with their corresponding values:

\frac{2(5+3)}{2*5}

Cancel out 2 in both numerator and denominator.

\frac{3+5}{5}

Add 3 and 5 to get 8.

\frac{8}{5}

Finally, divide 8 by 5 to get your answer:

\frac{8}{5} = 1.6

Your answer is (a) 1.6
