What is an equation of the line that passes through the points (0,7) and (5,4? Put your answer in fully reduced form.

gregori [183]

Answer <u>(assuming it can be in slope-intercept format)</u>:

$y = -\frac{3}{5} x+7$

Step-by-step explanation:

When knowing the y-intercept of a line and its slope, we can write an equation representing it in slope-intercept form, or $y = mx + b$ .

1) First, find the slope of the equation. Use the slope formula, $m = \frac{y_2-y_1}{x_2-x_1}$ , to find the slope. Substitute the x and y values of the given points into the formula and simplify:

$m = \frac{(4)-(7)}{(5)-(0)} \\m = \frac{4-7}{5-0} \\m = \frac{-3}{5}$

Thus, the slope is $-\frac{3}{5}$ .

2) Usually, we would have to use one of the given points and the slope to put the equation in point-slope form. However, notice that the point (0,7) has an x-value of 0. All points on the y-axis have an x-value of 0, thus (0,7) must be the y-intercept of the line. Now that we know the slope of the line and its y-intercept, we can already write the equation in slope-intercept format, represented by the equation $y = mx + b$ . Substitute $m$ and $b$ for real values.

Since $m$ represents the slope, substitute $-\frac{3}{5}$ in its place in the equation. Since $b$ represents the y-intercept, substitute 7 in its place. This gives the following equation and answer:

$y = -\frac{3}{5} x+7$

You deposit 700$ in an account with an annual internet rate of 4% after 5 years

alex41 [277]

Answer:

840

Step-by-step explanation:

Heres the easiest way to figure this out. You deposit $700 dollars into your account, correct? So, the annual interest rate is 4%. Take 700 dollars and multiply that by 4 percent. You get $28. So, EVERY. SINGLE. YEAR. you get 28$. So, multiply 28 by 5. Thats $140. Then, add 140 into 700, and you get 840.

Hope this helped!
