Answer:

\frac{1}{2} k-\frac{3}{5}

Step-by-step explanation:

Step 1: Define expression

\frac{2}{5} k-\frac{3}{5} +\frac{1}{10} k

Step 2: Change denominators to like terms

\frac{4}{10} k-\frac{3}{5} +\frac{1}{10} k

Step 3: Combine like terms

\frac{5}{10} k-\frac{3}{5}

Step 4: Simplify

\frac{1}{2} k-\frac{3}{5}

Write an equation in slope-intercept form of the line shown.
7nadin3 [17]

Answer:

y = 2x - 5

Step-by-step explanation:

Find the slope using the points, (1, -3) and (3, 1):

slope(m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 -(-3)}{3 - 1} = \frac{4}{2} = 2

m = 2

Find the y-intercept (b) by substituting x = 1, y = -3, and m = 2 in y = mx + b

-3 = (2)(1) + b

-3 = 2 + b

Subtract 2 from both sides

-3 - 2 = 2 + b - 2

-5 = b

b = -5

Plug in the value of m and b into the slope-intercept form equation, y = mx + b.

Thus:

y = 2x +(-5)

✅y = 2x - 5
