Question

if you graph two lines that are parallel and both crosses the x axis, what must be true about the x intercepts and slopes

Answer 1

Answer:

slopes - equal

x intercepts - different

Step-by-step explanation:

if you graph two lines that are parallel and both crosses the x axis, what must be true about the x intercepts and slopes

Equation of a line

y = mx + c

for two parallel line m remains the same

m is the slope of the line

so slopes of two parallel lines are equal

x intercepts means crossing x axis / y = 0

=> 0 = mx + c

=> x = - c/m

Now c can be different for parallel lines

so x intercept will be different for two parallel lines until or unless they are the same line.
