Answer:

y = 4x-7

Step-by-step explanation:

Slope intercept form is

y = mx+b where m is the slope and b is the y intercept

4x-y = 7

Subtract 4x from each side

-y = -4x+7

Multiply each side by -1

y = 4x-7

Which equation represents a line that is perpendicular to the line passing through (-4,7) and (1,3)?

diamong [38]

The equation perpendicular to the line passing through the points (-4,7) and (1,3) is $y=\frac{5}{4}x-2$

<h3>Equation perpendicular to a line</h3>

The slope of the given line is calculated as:

$m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{3-7}{1-(-4)} \\\\m=\frac{-4}{5}$

The equation perpendicular to the given line will be of the form

$y-y_1=\frac{-1}{m} (x-x_1)$

Substitute $x_1=-4, y_1=7, and m=\frac{-4}{5}$

$y-7=\frac{5}{4}(x+4)\\\\ y=\frac{5}{4}x+5-7\\\\ y=\frac{5}{4}x-2$

Therefore, the equation perpendicular to the line passing through the points (-4,7) and (1,3) is $y=\frac{5}{4}x-2$

Find the total charges if it takes the computer

Tom [10]

Answer:

225

Step-by-step explanation:

the person chages 40 per hour with a one time service charge of 65. our equation is 40h+65 where h equal hours. the person spend 4 hour so the equation is (40x4)+65. 40x4 is 160. 160 + 65 is 225
