Answer:
slope-intercept form: y=5x-3 point-slope form: y-7=5*(x-2)
Step-by-step explanation:
Y-y1=m(x-x1)
plug in the values and you get y=5x-3

Remember to use PEMDAS when solving these problems. You multiply before you work with addition and subtraction.
Step-by-step explanation:
Let x represent theta.

Using the angle addition trig formula,



Multiply one side at a time
Replace theta with x , the answer is

2. Convert 30 degrees into radian

Using tangent formula,


Tan if pi/6 is sqr root of 3/3

Since my phone about to die if you later simplify that,
you'll get

Replace theta with X.
