Write the slope-intercept form of the equation of the line with a slope of 3 and y-intercept of -8

(a)  

Write the point-slope form of the equation of the line through the point (5,4) and slope of 3.

(a)  

Find the slope of the line that passes through the points $$\left(-7,10\right)$$   and $$\left(3,10\right)$$  

Solve by elimination

$$-8x-2y=2\$$  

$$16x-y=1$$  

Enter your answer in the following format: (x,y)

(a)  

Solve by substitution

$$3x+24y=-8$$  

$$x+8y=3$$  

If a system of linear equations contains two lines have the same slope and the same y-intercept, how many solutions does the system have?

Select the graph of the solution to the system of inequalities:

$$y\le2x+2$$  

$$y>-\ \frac{1}{2}x-3$$  

Simplify $$-3\sqrt{50}$$  

True or False...

$$2\sqrt{45}+3\sqrt{20}=12\sqrt{5}$$  

Simplify $$4\sqrt{12}\cdot5\sqrt{3}$$
