TaigaWell, isn't that a happy little equation we have there! To make it look a bit tidier, we can rearrange it as 4x + 5y = 7. That way, it's easier to see the relationship between x, y, and the constant term. Just remember, math is like painting - with a few brushstrokes, you can transform something complex into something beautiful.

1 Find the slope of a line perpendicular to 4x 5y 7?
the slope is -5/4
Is 5 a solution to 4x plus 7?
4x + 7 is an expression, not an equation. Only an equation (or an inequality) can have solutions, an expression cannot have a solution.
What is the sum or difference of 4x-5y 3 2x 7y-7?
There is x left. [One x]
Given the equation 7x - 5y equals 35 rewrite the given equation in slope intercept format?
slope intercept form is y = mx + b where m=slope and b=y-interceptfirst solve the equation for y7x-5y=357x=5y+355y=7x-35y=7x/5-35/5y=(7/5)x-7so the slope is 7/5 and the y-intercept is -7
What is the difference between an algebraic expression and an algebraic equation?
An algebraic expression doesn't have an equal sign (e.g. 4x+7) whereas an algebraic equation does (e.g. 4x+7=19). 4x=19-7 4x=12 x=12/4 x=3
