This is not a solution to the equation.
Work Step by Step
In order to see if something is a solution to an equation, we plug in the (x,y) point to see if the equality is correct. Thus, we plug (-4,10) into y=10-5x to find: 10=10-5(-4) 10=10-(-20) A key rule to remember is that subtracting a negative is the same as addition. 10=10+20 10=30 10 does not equal 30, so this is not a solution to the equation.
