What is the slope of the line that passes through the points (2, 3) and (4, 5)?
The slope of the line is $m = (5 - 3)/(4 - 2) = 2/2 = 1$
What are the x and y intercepts of the line $2x + 3y = 12$?
The x-intercept is $x = 6$ and the y-intercept is $y = 4$
Graph the line $y = 2x - 3$ on the coordinate plane. What is the y-intercept and the slope of the line?
The y-intercept is $-3$ and the slope is $2$
Tom can paint a room in 4 hours, and his brother can paint the same room in 6 hours. How long will it take for them to paint the room together?
Let $t$ be the time it takes for them to paint the room together. Tom can paint $1/4$ of the room in 1 hour, and his brother can paint $1/6$ of the room in 1 hour. Together, they can paint $1/4 + 1/6 = 3/12 + 2/12 = 5/12$ of the room in 1 hour. Therefore, it will take them $t = 12/5 = 2.4$ hours to paint the room together
The cost of a bike is $80 more than 2 times the cost of a helmet. If the cost of the helmet is $x$, write an equation to represent the situation and solve for $x$ if the cost of the bike is $240.
Let $x$ be the cost of the helmet. Then, the cost of the bike is $80 + 2x$. We can set up the equation $80 + 2x = 240$ and solve for $x$. Subtracting $80$ from both sides, we get $2x = 160$, and dividing both sides by $2$, we get $x = 80$
