Answer:
ill just help you out with this-
the slopes are
5/4 and 7
Explanation:
so for question number 7 there are black dots right? those indicate that theyre exact points (because sometimes in a graph you dont know if its 6 or 6.1, cause sometimes theyre very close)
so the point on the left side is (-2, -2) because x is on the left side of the y axis (the vertical line). since its below the x axis (the horizontal line) its negative
for the point on the right its the opposite, because x is on the right x is positive. because x is above the x axis, its positive (but it can also be positive if its on the x axis, x = 0)
the point on the right is (2, 3)
so we substitute these points into the equation for the slope
3 - (-2) / 2 - (-2) it doesnt matter which way you put them, but if you put the first y (-2, 2) (the 2) then you have to put the x from the first point
but anyways
3 - (-2) / 2 - (-2)
simplify:
3 + 2 / 2 + 2
5 / 4
so the slope is 5/ 4
run 5 rise 4
for the graph..the graph is really easy lol i like graphs
but anyways for the graph the points are already given
when x is 2, y is 14
when x is 5, y is 35
when x is ____, y is blah blah blah
so now all you have to do is substitute two points into the equation. it doesnt matter which points because the slope will still be the same for example:
you can substitute (2, 14) and (5, 35)
35 - 14/ 5 - 2
21 / 3
7
and you can also substitute (5, 35) and (10, 70)
70 - 35/ 10 - 5
35 / 5
7
and its still the same slope
