Given the graph of a line, you can determine the equation in two ways, using slope-intercept form, y=mx+b y = m x + b , or point-slope form, y−y1= m(x−x1) y − y 1 = m ( x − x 1 ) . The slope and one point on the line is all that is needed to write the equation of a line.
Y2-Y1 -5-4 -9 -3
——— = ——— = —– it can reduce (GCF: 3) ——
X2-X1 10-(-2) 12 4
The slope is -3/4
Answer:
1
Step-by-step explanation:
Dy/dt = dy/dx * dx/dt
dy/dx = 6x^2 - 4
when x = 1, dy/dx = 6 - 4 = 2
dy/dt = 2 * 4 = 8.
X = dimes
6x = nickels
x + 6x = 91
7x = 91
x = 91/7 = 13
13 dimes and 78 nickels
