Answer:
f and b
Step-by-step explanation:
if you put them in y-intercept form, both slopes are 3
In b. it's easy to see that 3x has a slope of 3.
In f. it's not so obvious. Just solve for y or use the shortcut m = -a/b where a is the coefficient of x and b is the coeff of y.
hence -(6/-2)=3
Answer:
Step-by-step explanation:
assuming you know how to put the equations into y = m x + b already. All equations have to be put in that format to identify the slope. Parallel lines have the same slope.
a. y = -2x - 1; slope -2
b. y = 3x - 1; slope 3
c. y = 2x - 3; slope 2
d. y = 4x + 3; slope 4
e. y = x/2 - 1; slope 1/2
f. y = 3x; slope 3
g. y = x/3 + 4/3; slope 1/3
h. y = -x/2 + 5; slope -1/2
There are only 2 that are alike. b and f both have a slope of 3. all the other slopes are different.
