Through (-1,-1), slope of 4 what is the standard form equation of the line through the given point with a given slope

Vinvika [58]

Answer:

The equation of the line is -4x + y = 3

Step-by-step explanation:

Since we have the slope, we can use it and either point in point-slope form and solve for the standard form of the equation.

y - y1 = m(x - x1)

y - -1 = 4(x - -1)

y + 1 = 4(x + 1)

y + 1 = 4x + 4

-4x + y + 1 = 4

-4x + y = 3

Lynna [10]

Answer:

$\left \{ {{\theta_1=\frac{\pi }{4} } \atop {\theta_2=\frac{3\pi }{4} }} \right. .$

Step-by-step explanation:

$2*cos^2\theta-1=0\ \ \ \ (0^0\leq \theta\leq 360^0)\ \ \ \ \ \theta=?\\2*cos^2\theta-(sin^2\theta+cos^2\theta)=0\\2*cos^2\theta-sin^2\theta-cos^2\theta=0\\cos^2\theta-sin^2\theta=0\\cos2\theta=0\\0^0\leq \theta\leq 360^0\ \ \ \ \Rightarrow\\\left \{ {{2\theta=\frac{\pi }{2}\ |:2 } \atop {2\theta=\frac{3\pi }{2}\ |:2 }} \right. \ \ \ \ \left \{ {{\theta_1=\frac{\pi }{4} } \atop {\theta_2=\frac{3\pi }{4} }} \right. .$
