198 is the answer ok ok ok
Answer:
y = 3/5x - 1
Step-by-step explanation:
y = mx + b
m = slope
m = 3/5
to find the y - intercept we have to make x = 0 by adding or subtracting
in this case it is +5
add five to both x and y
the y intercept focuses on what y is when x is 0
the y intercept in this case is -1
Answer:
The factored form of the equation is (x + 4)(x – 6) = 0.
Answer:
7) A
8) 1/2
9) 5000
Step-by-step explanation:
7)
(0, 0), (4, -10)
The line goes through point (0, 0), the origin, so its equation is of the form
y = mx, where m = slope
m = (-10 - 0)/(4 - 0) = -10/4 = -5/2
Equation: y = -5/2 x
Answer: A
8)
(0, 0), (2, 1)
The line goes through point (0, 0), the origin, so its equation is of the form
y = mx, where m = slope
m = (1 - 0)/(2 - 0) = 1/2
Equation: y = 1/2 x
Answer: 1/2
9)
The value of the house increases $5000 per year, so we multiply the number of years, x, by 5000 to find the increase after x years.
Equation: y = 5000x
Answer: 5000
