Complete the equation of the line whose y-intercept is (0.-1) and slope is 4.
meriva
Well just by looking at the information provided, you can tell that the equation would look like y = 4x -1. The y-intercept is -1 because the x value is 0. But if you want to see how to solve it algebraically, here’s an explanation... You need to substitute the y-intercept into the equation in order to solve for b, which would then complete the equation. Take the equation y=mx+b. Substitute in the slope and xy values, (-1) = 4(0) + b. Now the equation should look like this: -1 = b. So now that you have the value of b, the complete equation should be y=4x-1

The graph represents the piecewise function
mr Goodwill [35]

The piece-wise function is defined as follows:

  • f(x) = x^2, 0 \leq x < 3.
  • f(x) = -\frac{5}{3}x + 14, 3 < x \leq 6.
  • f(x) = \frac{3}{2}x - 5, 6 \leq x \leq 10.

<h3>What is a piece-wise function?</h3>

A piece-wise function is a function that has multiple definitions, depending on the input.

In this graph, for x at least 0 and less than 3, the parabolic curve passes through (0,0), (1,1), (2,4) and has an open interval at (3,9), hence the definition is:

f(x) = x^2, 0 \leq x < 3

For x greater than 3 and at most 6, it is a line going through (3,9) and (6,4), hence:

m = \frac{9 - 4}{3 - 6} = -\frac{5}{3}

f(x) = -\frac{5}{3}x + b

Goes through (3,9), hence:

9 = -\frac{5}{3}(3) + b

b = 14.

So

f(x) = -\frac{5}{3}x + 14, 3 < x \leq 6

For x between 6 and 10, it is a line going through (6,4) and (10,10), hence:

m = \frac{10 - 4}{10 - 6} = \frac{6}{4} = \frac{3}{2}

Then:

f(x) = \frac{3}{2}x + b

When x = 10, f(x) = 10, hence:

10 = \frac{3}{2}(10) + b

10 = 15 + b

b = -5.

Hence:

f(x) = \frac{3}{2}x - 5, 6 \leq x \leq 10
