Answer:
y=-3x+4
Step-by-step explanation:
The question is asking for the equation in slope-intercept form. This is y=mx+b where m is the slope and b is the y-intercept.
The slope can be found by counting the units in between two points on the graph. Remember that slope is rise over run or y/x. Two points on the graph are (2,-2) and (1,1). The y is increasing by 3 while x is decreasing by 1. This means the slope is -3.
The y-intercept is where the line intersects with the y-axis. In this case, that point is (0,4). Therefore, b=4.
The final answer is y=-3x+4.

<h2><u>Q</u><u>u</u><u>e</u><u>s</u><u>t</u><u>i</u><u>o</u><u>n</u>:-</h2>
The equation of the function is y = 4x + 5. Find the value of y when
x = 3
x = -2
<h2><u>A</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u>:-</h2>
<h3>Given:-</h3>
y = 4x + 5 [Equation]
<h3>To Find:-</h3>
The value of y when x = 3 , x = -2
<h2>Solution:-</h2>
y = 4x + 5 [Given equation]
When x = 3 ,
y = 4 × 3 + 5 [Value of x is 3]
y = 12 + 5
<h3>y = 17 [Answer]</h3>
Again, when x = -2 ,
y = 4 × (-2) + 5 [Value of x is -2]
y = -8 + 5
<h3>y = -3 [Answer]</h3>
