URGENT HELP What is the equation of the line that passes through the point (-7, -4) and has a
shepuryov [24]

The final equation is:

y=x+3

Further explanation:

The general form of equation of a line in slope-intercept form is:

y=mx+b

Here m is the slope

Given

m=1

(x,y) = (-7,-4)

Putting\ the\ value\ of\ slope\ in\ equation\\y=(1)(x)+b\\y=x+b

To find the value of b, we have to put the point in the equation

-4=-7+b\\-4+7=b\\b=3

The final equation is:

y=x+3

Keywords: Slope-intercept form, equation of line

Please help I have no clue how to do this​
Alinara [238K]

Step-by-step explanation:

It's a question of trigonometry.

You need to remember that tangent (tan) stands for Perpendicular / Base.

So, tan P = QR / PR

By Pythagoras Theorem,

34² = 30² + x²

x² = 34² - 30²

x² = 1156 - 900

x² = 256

x = 16

Now, placing the values,

tan P = 30 / 16

tan P = 1.875

HOPE IT HELPS ^_^
