What is the slope and the y-intercept of the graph of the linear function shown on the grid ?
VladimirAG [237]

Answer:

Slope: -1/4; Y-Intercept: 1.5

Step-by-step explanation:

Step 1: Find the slope. The best way to do this is to transform the two given points to y=mx+b form. When given two points, the best way to find the slope will be to do y2-y1/x2-x1. In this equation it would be -2-0/2+6, which is -2/8, simplified is -0.25 or -1/4. So we have the slope, which can determine the length of the line.

Step 2: Find the Y-Intercept. Finding the Y-intercept is so much simpler when given a graph, since all you have to do is find where the line goes through the y-axis, which in this case is (0,1.5), meaning that the y-intercept is 1.5 <em>(note: the y-intercept can also be found when x=0, for example (0,9).</em>

Hope this helped, good luck!

miskamm [114]
The formula q \Rightarrow p means that from statement q implies statement p. 

When statements p="two linear functions have different coefficients of x" and q="the graphs of two functions intersect at exactly one point", then the statement q \Rightarrow p have a form: "If the graphs of two functions intersect at exactly one point, then two linear functions have different coefficients of x."
