Answer:
The difference in slopes of is = 3
We can say slope of is positive and 3 more than slope of
while slope of
is negative.
Difference of y-intercepts of is = -7
We can say the y-intercept of is positive and 7 units above
while y-intercept of
is negative.
Step-by-step explanation:
Given equation:
We need to find the difference of slopes and y-intercepts of the given equations.
The standard form of a slope intercept equation of line is given by:
where represents slope and
represents y-intercept of line.
Writing the given equations in standard form to find slope and y-intercept.
Slope = 2 and y-intercept =-2
Slope = -1 and y-intercept =5
The difference in slopes of is =
We can say slope of is positive and 3 more than slope of
while slope of
is negative.
Difference of y-intercepts of is =
We can say the y-intercept of is positive and 7 units above
while y-intercept of
is negative.
