which pair of the following straight lines are parallel and how?a. 2x + y + 1 = 0b. y = 3x - 1c. 2x - y = 3d. y = 4x + 3e. y = x/2 - 1f. 6x - 2y = 0g. 3y = x + 4h. 2y = 5 - x
Accepted Solution
A:
Answer:f and bStep-by-step explanation:if you put them in y-intercept form, both slopes are 3In 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
