Answer:
Step-by-step explanation:
Given line is,
y=-4x+3
when, x=-1 , y=-4(-1)+3=4+3=7
when, x=0 , y=-4(0)+3=0+3=3
when, x=1 , y=-4(1)+3=-4+3=-1
So, we got the points (-1,7) , (0,3) , (1,-1)
Now, putting the points in the graph and adding them , we will get the graph of given line.
Please check image for the graph.
Now for the second part-
The graph is positive means- it will be above the x-axis, that is y value will be positive.
From the graph we can see that, if x<0 , then y is positive.
So, any value of x which is less than 0 , will give the positive graph here.
Answer:
y = x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 4, 0) and (x₂, y₂ ) = (0, 1)
m = =
Note the line crosses the y- axis at (0, 1) ⇒ c = 1
y = x + 1 ← equation of line
