Answer:
the correct graph is A
Step-by-step explanation:
Note that the red line passes through (0, 2), which is the y-intercept, b, in y = mx + b. Thus the correct answer must be A or B, not C or D.
Besides (0, 2), another point on this line is (1, 3).
The increase in x going from 0 to 1 is 1; this is the 'run'. That in y going from 1 to 3 is 2; this is the 'rise.' Therefore the slope is m = rise / run = 2/1 = 2.
Thus the correct graph is A; its slope is 2 and its y-intercept is 1.
