The slope of the line that contains the points (1, -1) and (2, 3) is 4. What is the y-intercept?
Answers
y-y1=m(x-x1)
y-(-1)=4(x-1)
y+1=4(x-1)
y+1=4x-4
y=4x-4-1
y=4x-5
Or
y=4x+b
-1=4(1)+b
-1=4+b
-1-4=b
-5=b. Y-intercept is -5
The y-intercept of the line is -5.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
We can use the slope-intercept form of a linear equation to find the
the y-intercept of the line.
The slope-intercept form of a linear equation is:
y = mx + b
where m is the slope of the line, and b is the y-intercept.
We are given the slope of the line that contains the points (1, -1) and
(2, 3) is 4.
Therefore, we can substitute m = 4 and one of the points into the equation, and solve for b.
Let's use the point (1, -1):
y = mx + b
-1 = 4(1) + b
-1 = 4 + b
b = -1 - 4
b = -5
The y-intercept of the line is -5.
The equation of the line in slope-intercept form is:
y = 4x - 5
Thus,
The y-intercept of the line is -5.

Multiply 0.79 and 0.65 (65%) which is about 0.51.
Add that to 0.79.
Answer:
$ 1.30
Step-by-step explanation:
Increased price = 65% of $0.79
[tex]\frac{65}{100}*0.79[/tex]
