Y = mx + c.
m = the gradient : i.e. The slope
c = the y intercept, (where the line passes through the y axis)
The slope (gradient/) = 2
So now you have y = 2x + c
You have also been told that the y intercept is 1
So now you have the equation : y = 2x + 1
The line on a graph goes up, as the gradient is positive.
It is also a straight line as the x has a indices of 1.

Y = mx + b

in this case m = 2 and b = 1 so
equation
y =2x + 1

hope this helps

graph the solution to the following system of inequalities y<-2x+7, y greater than or equal to 2x - 3

Alex777 [14]

Answer:

See attached diagram

Step-by-step explanation:

Graph the solution of the inequality $y$ First, draw the dotted line $y=-2x+7$ (dotted because the sign of the inequality is <). Then determine wich part of the coordinate plane should be shaded. Since the origin's coordinates satisfy the inequality, then this point should belong to the region (red part on the diagram).

Graph the solution of the inequality $y\ge 2x-3.$ First, draw the solid line $y=2x-3$ (solid because the sign of the inequality is ≥). Then determine wich part of the coordinate plane should be shaded. Since the origin's coordinates satisfy the inequality, then this point should belong to the region (blue part on the diagram).
