Convert from standard to slope intercept form 3x -y= -1

y= 3x + 1

Step-by-step explanation:solve for y

subtract 3x from the left  which leaves -y= -3x -1

then you have to take flip the signs or divide by -1  so it comes out to y=3x + 1

y = 3x + 1

Step-by-step explanation:

Slope Intercept form is written out as the following:

y = mx + b

In order to convert "3x - y = -1", we first subtract 3x from both sides, giving us:

-y = -3x - 1

Since we have "-y", we multiply -1 on both sides.

-1(-y) = -1(-3x - 1)

Multiplying two negatives makes a positive, hence when we multiply -1 on both sides, it becomes this:

y = 3x + 1

So converting to the Slope Intercept form ends up being "y = 3x + 1"

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign
