Answer:
y = 4x + 8
Step-by-step explanation:
The slope intercept form for an equation is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x = 0).
m, the slope, is 4
y = 4x + b
We need a value of b that will force the line through point (3,20). Enter that point in the above equation and solve for b:
y = 4x + b
20 = 4*(3) + b for (3,20)
20 = 12 + b
b = 8
The equation becomes <u>y = 4x + 8</u>
See attachment.
bearing in mind that the hypotenuse is never negative, since it's just a distance unit, so if an angle has a sine ratio of -(5/13) the negative must be the numerator, namely -5/13.
le's bear in mind that the sine is negative on both the III and IV Quadrants, so both angles are feasible for this sine and therefore, for the III Quadrant we'd have a negative cosine, and for the IV Quadrant we'd have a positive cosine.
