Answer:
Step-by-step explanation:
y = (x - 2)(x + 5) First I would multiply (x - 2) and (x + 5) together
y = x² + 5x - 2x - 10
y = x² + 3x - 10
Next I would plug in a number for x to find its y value. I will plug in 0
y = 0² + 3(0) - 10
y = -10
(0, -10) [this is the y-intercept (the y value when x = 0)]
Your answer is Graph A because the y-intercept is (0,-10)
Answer:
B
Step-by-step explanation:
x² + y² = 3 creates a circle and circles are not functions because one x-value relates to two y-values instead of one
Answer:
M is the slope
Step-by-step explanation:
In the equation y=mx+b the slope is the number “m” that is multiplied by the x and “b” is the y intercept
