No because they don't have the same slope (9x & 3x)
y = 3/2 x + 7
3x + y = 7 First, turn the equation into the slope-intercept form, y = mx + b, where m is the slope of the graph that that equation represents (solve for y).3x + y = 7 subtract 3x to both sidesy = -3x + 7So you clearly see that the slope is -3.
Slope of given line = -3 Therefore, slope of perpendicular = 1/3
3x plus 9 equals what?
y intercept 7 x intercept 7/3
4x plus 7 plus 3x equals 19 plus xx = 2
3x+7=4x 7=4x-3x 7=x
Solve for y 3y=-7x+9 y=-7/3x+3 the slope is the coefficient of x in this case, it is -7/3
3x+7=37 -7 -7 3x=30 /3 /3 x=10
3x + 2y = 7
