9. The coordinate point (–4, 5) is located in quadrant II?

Question

True
False

10. The line y = x has a slope of 1.

True
False

Answer 1

Problem 9:

(-4, 5)....

so x = -4... so walk 4 steps to the left of the origin (0,0)...

and y = 5... so walk up 5 notches...

Yes... TRUE... the point (-4, 5) is located in quadrant II

Problem 10:

y = x.... is already in the general line equation y = mx + b format... where m is the slope... and b is the y-intercept...

so... in y = x.... that is the same as saying y = 1x....

so m = 1.... and and the statement is TRUE.

Answer 2

Both are true.
9. If x < 0 and y > 0 we are in quadrant II.
10. y= mx +b is the general form. m is the
slope and b is the y intercept.
If y = x then m=1, so the slope is 1.
