Answer:
y = 3x + 2; y = -x + 4
Step-by-step explanation:
Slope intercept form is in y = mx + b, where m is the slope and b is the y-intercept. In the first image, 2 is the y-intercept and 3 is the slope, yielding the equation y = 3x + 2.
For the second, 4 is the y-intercept and -1 is the slope, so the answer to the second image is y = -x + 4.
