This is an example I put a dot where -2 3/4 should be
Answer:
slope: 5
y-intercept: 3
therefore y=5x+3
Step-by-step explanation:
the slope is the value that is changing; as time passes the price increases by $5 per hour
the y-intercept is where the function crosses the y-axis (when x is 0); so when no time has passed.
Answer:
The answer is: y = 3x - 7
Step-by-step explanation:
Given point: (5, 8).
Slope m = 3
Use the point slope form and solve for y:
y - y1 = m(x - x1)
y - 8 = 3(x - 5)
y - 8 = 3x - 15
y = 3x - 15 + 8
y = 3x - 7
Proof:
f(x) = 3x - 7
f(5) = 3(5) - 7
= 15 - 7 = 8, giving (5, 8)
Answer:
y = 4/5 x + 2/5
Step-by-step explanation:
its none of them? 6y - 10/5 +7y = 12 10 divided by 5 equals 2
it will now look like this: 6y - 2 + 7y = 12
then your going to want to add 2 to both sides of the equation.
it will now look like this: 6y -2 + 7y + 2 = 12 + 2 = 14
simplify: 6y + 7y = 14
add the like terms: 13y = 14
