Answer <u>(assuming it can be in slope-intercept form)</u>:
Step-by-step explanation:
1) First, use the slope formula to find the slope of the line. Substitute the x and y values of the given points into the formula and solve:
So, the slope is .
2) Now, use the slope-intercept formula to write the equation of the line in slope-intercept form. All you need to do is substitute real values for the
and
in the formula.
Since represents the slope, substitute
for it. Since
represents the y-intercept, substitute 3 for it. (Remember, the y-intercept is the point at which the line hits the y-axis. All points on the y-axis have an x-value of 0. Notice how the given point (0,3) has an x-value, too, so it must be the line's y-intercept.) This gives the following equation and answer:
The required mixed number is . The calculations are attached with the solution as an image.
What is a mixed number ?
- A bit represented with its quotient and remainder is a mixed bit. For illustration,21/3 is a mixed bit, where 2 is the quotient, 1 is the remainder.
- So, a mixed bit is a combination of a whole number and a proper bit. A mixed bit, also called a mixed number, is a whole number and a bit together.
- The bit is written to the right of the whole number.
- A mixed number is formed by combining three corridor a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper bit that makes the mixed number.
