Which of the following has the same slope as the equation Y=1/2x-10?

a
1/2x - y = 10
b
-x + 3y = 12
c
-1/2x + y = -10
d
-2x + y = -6

c. -1/2x + y = -10

Step-by-step explanation:

Changing the order of the equation, you can verify the coefficient of x is the same when y is isolated.

In slope-intercept form, the coefficient of x, or the m in y=mx+b, is the slope or gradient.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
