Give the slope and y-intercept of the line whose equation is given below. Then graph the linear function. y equals -7x + 5
The slope of the line is -7? (Simplify your answer.)
The y-intercept is 5? (Type an integer or a simplified fraction.)
Use the graphing tool to graph the linear equation. Use the slope and y-intercept when drawing the line.
Please help verify, I don't understand the calculation to graph the linear function?
Slope and intercept are correctly identified.
To draw the line, use the coordinates point system.
(A) When x = 0, we get y = -7*0 + 5
y = 0 + 5 = 5
So, First point is (0,5)
(B) When x = 1, we get y = -7*1 + 5
y = -7 + 5 = -2
So, second point is (1,-2)
(C) When x = -1, we get y = -7*(-1) + 5
y = 7 + 5 = 12
So, third point is (-1,12)
hence, we need to make a line passing through the coordinate points (0,5), (1,-2) and (-1,12)
