2. select the equation in which the graph of the line has a negative slope, and the y-intercept equals 10.
a. 20x + 5y = 50
b. 10x + 5y = -25
c. 2x + 6y = 10
d. 5x - 10y = -12

3. select the equation that contains the point (-6, 1) and in which the slope equals 1/4
a. y + 1 = 1/4(x − 6)
b. y − 1 = 1/4x + 6
c. y − 1 = 1/4(x + 6)
d. y + 1 = 1/4x − 6

4. select the equation which contains the point (5, -1/2) and has a slope of 4
a. y − 1/2= 4(x +5)
b. y − 1/2=4(x − 5)
c. y + 1/2= 4(x + 5)
d. y + 1/2= 4(x − 5)
