y=-3x+4 someone please help me thank you
Of course! It looks like you have an equation in the form of y = -3x + 4. This equation represents a linear relationship between x and y. The equation tells us that for any value of x we plug in, we can calculate the corresponding value of y by using the equation.
To understand this equation better, let's break it down step by step:
1. The equation starts with "y =" which means we're finding the value of y.
2. Next, we have "-3x". The coefficient -3 in front of the 'x' represents the slope of the line. In this case, the line has a slope of -3, which means for every increase of 1 in x, y will decrease by 3. If the slope was positive, y would increase as x increases.
3. Lastly, we have "+ 4". This term represents the y-intercept, which is the value of y when x is equal to zero. In this case, the y-intercept is 4, meaning the line crosses the y-axis at the point (0, 4).
So, to find the value of y for a given x, plug the x-value into the equation and perform the calculations. For example, if you substitute x = 2 into the equation, you would get:
y = -3(2) + 4
y = -6 + 4
y = -2
Therefore, when x = 2, y = -2.
