Need quick.
1. write the standard form of the line that contains a slope of 1/2 and y -intercept of 3. include your work in your final answer.
2. write the standard form of the line that passes through the given points.
(-1, -3) and (2, 1)

Hello there,

1. The standard form of a straight line with a slope and a y-intercept is as follows:

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

In this case, we have a slope of and a y-intercept of 3. Plugging in for and 3 for gives us:

2. We are given two points. With these two points, we can find the slope with the formula for the slope to be:

We can use the points and the corresponding values to solve for the slope:

We can plug into our equation:

To find b, we simply plug in one of our points into this equation, and solve. I will use (2, 1) since both values are positive, but feel free to use (-1, -3) if you'd like:

Now plug into the equation.

Hope this helps! :^)

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
