Slope =-3
Y-intercept = =4
as an ordered pair it would be (-3, 4)

Explanation:

In this equation, the line is linear and so it has the formula y=mx+b . The m value is the slope, and so with our equation y=-3x+4, the m value is the coefficient directly in front of the x value, and so the slope is -3.

The y-intercept is the y value when the line cuts through the y-axis. We know that the line will always cut through the y-axis at x=0, and so in the equation y=-3x+4, we set x to 0.

y=-3x+4
y=-3(0)+4
y=4

The slope is m=-3
The y-intercept is (0,4)

Explanation:

The equation of a line is y=mx+b
where the value of the slope =m
and the y-intercept =b

For the equation y=4-3x
we can rearrange the values into the standard form of
y=mx+b
y=-3x+4

now m=-3 the slope
and b = 4 the y-intercept
The line would cros the y-axis at y=4 and x=0
giving the cordinate ordered pair #(0,4)

graph{y=-3x+4 [-10, 10, -5, 5]}
