Which is an equation of a line with an x-intercept of -4 and a y-intercept of 3? A. Y= 3/4x-4 B. y=3/4x+3 C. Y=-3/4x-4 D. Y=-3/4
x+3
1 answer:
Answer:
B. y = 3/4x + 3.
Step-by-step explanation:
Using the general form y = mx + c where m = the slope and c the y-intercept we have
Y = mx + 3
The x intercept is at (-4, 0) ( that is x = -4 when y = 0), so:
0 = m(-4) + 3
-4m = -3
m = 3/4
The answer is y = 3/4 x + 3.
