The equation of a line in point-slope form is expressed as:
y = mx + b
- m is the slope of the line
- b is the y-intercept
Given the inequality -2y > 7x + 4, this can also be expressed as:
-2y > 7x + 4
y < -7/2x -4/2
y< -7/2x - 2
This shows that the line will be a dashed line and cuts the y-axis at y= -2

Answer:
x-intercept: <u>(1,0)</u>
y-intercept: <u>(0,1)</u>
Step-by-step explanation:
Given: Find the x and y intercepts of 2x + 2y = 2
<h2><u>X-intercept</u></h2>To solve for a x - intercept we have to substitue 0 in for y and solve for
Lets do it:
2x + 2(0) = 2
2x + 0 = 2
2x = 2
x = 1
Therefore, this means that when y = 0, x = 1 or (1,0)
<h2><u>Y-intercept</u></h2>
To solve for a y - intercept we have to substitue 0 in for x and solve for
Lets do it:
2(0) + 2y = 2
0 + 2y = 2
2y = 2
y = 1
Therefore, this means that when x = 0, y = 1 or (0,1)
