which equation describes a line that contains the point (4,3) and is perpendicular to the line represented by the equation y=2/5x+3?

The equation of the line  that contains the point (4,3) and is perpendicular to the line represented by the equation y=2/5x+3 will be:

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where

Given the line

y=2/5x+3

comparing with the  slope-intercept form of the line equation

Thus, the slope of the line is: m = 2/5

We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:  

slope = m = 2/5

Thus, the slope of the the new perpendicular line = – 1/m = [-1]/[2/5] = -5/2

Using the point-slope form of the line equation

substituting the slope of perpendicular line m = -5/2 and the point (4, 3)

Add 3 to both sides

Therefore, the equation of the line  that contains the point (4,3) and is perpendicular to the line represented by the equation y=2/5x+3 will be:

step-by-step explanation: where's the phrase?

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
