The x intercept is that point at which curve cross the x axis and y intercept is the point at whcih curve intersect y axis.
As the curve cross the x axis at point (-1.2,0) and cross the y axis at (-0.7,0).
So x intercept is -1.2 and y intercept is -0.7.
y = -1x + 2
Put the points in the slope equation to find (-1 as m, -2 as x, and 4 as y)
y = mx + b
4 = -1(-2) + b
4 = 2 + b
4 - 2 = b
2 = b
Final equation: y = -1x + 2
Answer:
x = 3√5
Step-by-step explanation:
we can use the Pythagorean Theorem twice, first to find the longer leg of the left triangle:
7² + b² = 10²
b² = 100-49
b² = 51
b = √51 which we can simplify to be √9·√3·√3 = 3·3 = 9
we can use the Pythagorean Theorem next to find 'x':
x² + 6² = 9²
x² + 36 = 81
x² = 45
x = √45 = √9·√5 or 3√5
