How many soultions does the system of equations have y= -6x + 330x + 5y = 15a. one b. twoc. infinity manyd. none

Step-by-step explanation:

The slope-intercept form of an equation of a line:

m - slope

b - y-intercept

If the equations have the same slopes and the same y-intercepts, then the system of equations has infinitely many solutions.

If the equations have the same slopes and differences of the y-intercepts, then the system of equations has no solution.

If the equations have different slopes, then the system of equations has one solution.

We have

→ m = -6 and b = 3

and

convert to the slope-intercept form:

              subtract 30x from both sides

            divide both sides by 5

→ m = -6 and b = 3

We have the same slopes and the same y-intercepts.

option: d is correct

step-by-step explanation:

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral
