What is the equation of this graph? coordinates: (1,7), (0,0),(-1,-7)

y = 7x

Step-by-step explanation:

Slope: (7-0)/(1-0) = 7

y-intercept is obviously 0

y = 7x + 0

y = 7x

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.  

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
