To find the answer, see if the point is going to the left or to the right. If it is going to the left, it is less than. If it is going to the right it is greater than. Next find if the point is closed (shaded in) or open (not shaded in). If it is closed, it is equal to, if it is open, it is not equal to. Ex: Closed to the right - Greater than or equal to.

Answer: x = 0 , y = -4
Step-by-step explanation:
4x - 3y = 12 } Equation 1
y = 7x - 4 } Equation 2
<em>We can substitute the value of y from equation 2 in equation 1: </em>
4x - 3(7x - 4) = 12
4x - 21x + 12 = 12
-17x = 12-12
-17x = 0
x = 0
<em>Now we can substitute this value of x in equation 2 :</em>
y = 7x - 4 } Equation 2
y = 7·0 - 4 = -4
Answer: x = 0 , y = -4

The answer to your question is -4
Hello there! Slope is rise/run. The formula for finding slope is y2 - y1/ x2 - x1, meaning that you subtract the first y-coordinate from the second y-coordinate and the first x-coordinate from the second x-coordinate. The points we are using are (-4, 0) and (1, -5). Let's plug in the values: -5 - 0 / 1 - (-4). Okay. When we subtract a negative number, we actually add the number. Do the math, and you get -5/5 or just -1. The slope of the line is -1. The formula will be transferred into slope-intercept form, which is y = mx + b, with "m" being the slope, "b" being the y-intercept (where the line crosses the y-axis, with the value of x-axis being 0), and "y" and "x" remaining unfilled. The y-intercept is -4. The formula in slope-intercept form is y = -1x + (-4).
