What is the proportion of k/7=k+13/8?

1 answer:

7 0

K = k + 1378 Cross multiply: K * 8 = 7 * k + 13 Simplifying K * 8 = 7 * k + 13 Reorder the terms for easier multiplication: 8K = 7 * k + 13 Reorder the terms: 8K = 7 * 13 + k 8K = 13 * 7 + k * 7 8K = 91 + 7k Solving 8K = 91 + 7k Solving for variable 'K'. Move all terms containing K to the left, all other terms to the right. Divide each side by '8'. K = 11.375 + 0.875k Simplifying K = 11.375 + 0.875k

A line that include the point (0,2) has a slope is -1/7 what is its equation in slope-intercept form?

Kitty [74]

Answer:

y = -(1/7)x+2

Step-by-step explanation:

A slope-intercept form is y = mx + b, where m is the slope and b the y-intercept (the value of y when x=0).

We're given the slope: m = -(1/7):

y = -(1/7)x + b

We can use the given point, (0,2) in this equation and solve for b:

y = -(1/7)x + b

2 = -(1/7)*(0) + b

b = 2

The equation becomes y = -(1/7)x + 0

y = -(1/7)x+2
