Problem: 1.4x-7.9y+6.4=0 what is the x intercept and the y intercept of the line give by equation
what is the x intercept and the y intercept of the line give of the equations 1.4x-7.9y+6.4 =0
1.4x - 7.9y + 6.4 = 0
-7.9y = -1.4x - 6.4
y = 0.1772x + 0.810
The intercepts are found by setting x and y to zero, in turn,
and calculating the other one. Setting x to zero gives the y-intercept.
y = 0.1772(0) + 0.810
y = 0 + 0.810
y = 0.810
Setting y to zero gives the x-intercept.
0 = 0.1772x + 0.810
-0.1772x = 0.810
x = -4.572
The x-intercept is (-4.572, 0)
The y-intercept is (0, 0.81)
