Answer:

Step-by-step explanation:

The slope-intercept form is found by solving that equation for y.

If y-3=\frac{1}{2}(x-1) then

y-3=\frac{1}{2}x-\frac{1}{2} and

y=\frac{1}{2}x-\frac{1}{2}+3 and

y=\frac{1}{2}x-\frac{1}{2}+\frac{6}{2} so

y=\frac{1}{2}x+\frac{5}{2}

The answer you have chosen is the correct one!  Good job!

Solve equation 3k+45=8k+25
Brrunno [24]

Answer:

k=4

Step-by-step explanation:

First, we can subtract 3k on both sides. It is ultimately easier to start by subtracting the term with a variable. This would result in 45=5k+25. Then, we can subtract 25 on both sides to get closer to isolating k. This becomes 20=5k. We can then divide by 5 on both sides. This means that k=4.
