Y = -8 simply means for every x coordinate the y coordinate is -8, therefore it creates a horizontal line at y = -8.
X intercepts are when y = 0. Y intercepts are when x = 0.
In this case of the line, y = -8 there is no x intercept because y doesn’t equal 0.
However there is a y intercept at (0,-8) because y is -8 for every input including 0.
If you have any other questions feel free to ask.
First we calculate the slope (which is called "m".
Slope = m = (Y2 -Y1) ÷ (X2 -X1)
m = (-8 -1) / (5 -2) = -9 / 3 = -3
We next fill in this equation: b = y -mx
We know m = -3 and we can choose a point (2, 1) to calculate "b"
b = 1 --3 * 2 b = 7
Putting this into y = mx +b
y = -3x +7
Answer:
x^2 - 2x + 4
Step-by-step explanation:
Answer:
The first one: 19/15a
second one: b²-4ac = D
Step-by-step explanation:
for first one: take LCM and solve
for second one: you square the expression on both sides then b²= D + 4ac, then when you take 4ac to the left hand side, it becomes b²-4ac= D
