Answer:
Step-by-step explanation:
y = 4x+2
slope of the line is 4
slope of any parallel to the line is also 4
point-slope equation for line of slope 4 that passes through (8,4):
y-4 = 4(x-8)
rearrange to slope-intercept form:
y = 4x - 28
Answer:
y=-2/5x
Step-by-step explanation:
y-y1=m(x-x1)
y-(-2)=-2/5(x-5)
y+2=-2/5(x-5)
y=-2/5x+10/5-2
y=-2/5x+2-2
y=-2/5x
Answer:
Graph of a one-to-one function if f is a one-to-one function then no two points (x1,y1), (x2,y2) have the Same y-value. Therefore horizontal line cuts the graph of the equation y = f (x) more than omce. Horizontal line test: A graph passes the horizontal line test if each horizontal line cuts the graph at almost once.
