Which equation represents a line that has a slope of -5 and an X- intercept of 7?

Solve for x by completing the square. 2x^2-4x+7=0

Which mathematical statements are true? 1) if 3 is an odd number, then 3 times 3 is an even number. 2) if 6 is less than 7, then 4 is greater than 7. 3) six is divisible by 3, and 10 is a multiple of 2. 4) the average of the data is greater than the largest value in the data, or it’s less than the largest value in the data. 5) the slope of a linear graph is its rate of change, and the graph’s y-intercept is the initial value. 6) if an equilateral triangle has equal angles, then all its angles will measure 45°.

The ratio of the measures of the three angles in a triangle is 2: 9: 4. find the measures of the angels
