Write a linear equation that does not intersect the graph of y=-2x+3 and has an x-intercept of 1. Explain your reasoning.

Answer:
y =-2x+2
Step-by-step explanation:
We want a line that does not intersect y = -2x+3
It must be parallel to this line, so it must have the same slope (Parallel lines have the same slope)
The slope is -2
We have an x intercept of 1 (1,0)
The have the slope and a point
We can use the point slope form of a line to write the equation
y-y1 = m(x-x1)
y-0 = -2(x-1)
Distribute
y=-2x+2
y =-2x+2
This is in slope intercept form
