Graph y= –3x+4. (I WILL MARK BRAINLIEST)
1 answer:
Answer:
See attached
Step-by-step explanation:
<u>Given function:</u>
- y= –3x + 4
To graph the line we need two points
One of the easy points is the y-intercept:
- (0, 4)
Another point can be taken depending on the slope. With the slope of -3, we select x = 2 and find its y- coordinate:
- y = -3(2) + 4 = -6 + 4 = -2
So we have points
- (0, 4) and (2, -2)
Plot these points and connect with the line and we are done.
