how can I find the slope to this I need help​

Answers

Answer:

Your slope is -1

Step-by-step explanation:

Find the change in x and the change in y and put it in change in y over change in x.

Δx = -1 - -2 = 1

Δy = -1 - 0 = -1

Slope = rise over run = Change in y over change in x =  Δy/Δx = -1/1

Therefore the slope is -1/1 which is written as just -1

A line has a slope of 3 and passes through the point (4, 7). What is its equation in
slope-intercept form?

Answers

Answer:

Step-by-step explanation:

y - 7 = 3(x - 4)

y - 7 = 3x - 12

y = 3x - 5

The equation of the line in slope intercept form having slope 3 and passing through the point (4, 7) is y = 3x - 5.

What is Slope?

Slope of a line is the rise over the run of the given line. It is usually denoted by m.

In other words, Slope of a line can be calculated by finding the difference of the y coordinates divided by the difference of the x coordinates where x coordinate and y coordinate of two points are given.

Equation of a line in slope intercept form is given by

y = mx + c

where, m is the slope and c is the y- intercept.

Now y-intercept is the y-coordinate of the point where x = 0 or when the line touches the Y axis.

Here, m = 3

We have a point (x, y) = (4, 7)

Substituting these values in the equation,

7 = (3 × 4) + c

7 = 12 + c

c = 7 - 12

c = -5

Substituting m = 3 and c = -5,

y = 3x - 5

Hence, the equation of the line passing through the point (4, 7) and with a slope of 3 is y = 3x - 5.

Here you go. I hope you get it.

The graph of the equation y = 8x - 6 is a straight line.

What is slope intercept form?

The slope intercept formula y = mx + b is used when you know the slope of the line to be examined and the point given is also the y intercept

(0, b).

Given is an equation, y = 8x - 6

Finding the coordinates,

Put x = 0, y = -6

(0, -6)

Put y = 0

8x = 6

x = 0.75

(0.75, 0)

Plotting the graph,

Hence, we will get a straight line of the graph.

Answers

The account must pay a 40 percent interest rate under Marcos.

A basic interest account is what?

A loan's or deposit's initial principal serves as the foundation for simple interest.

Contrarily, compound interest is calculated based on both the principal amount and the interest that is accrued on it each period.

Simple interest is simpler to compute than compound interest because it is just applied to the principal.
